Oregon Projection: Obama by 13



I have beaten this particular horse to death, but if you went looking for a state that is white and working class, Oregon wouldn't be a bad place to end up. Just 1.6 percent of Oregonians are African-American (though it does have its share of Hispanic and Asian voters). It ranks below the national average in income levels while having one of the nation's higher unemployment rates.

And yet, there may be something about Oregon's political DNA that's a little different. As I mentioned previously, Oregon has the most left-leaning Democratic electorate in the country. The problem is that the relationship between ideology and voting patterns has been murky thus far in the primaries. Clinton did quite well for herself in states like Massachusetts and New Hampshire, which also have quite liberal electorates. But more recently, she has tended to excel in conservative areas.

I checked to see whether there was a time trend in the data and in fact there was. When the election cycle began, Obama was actually outperforming Clinton in Republican-leaning districts. In a district with a rating of R+10, for example (one where George Bush performed ten points better than his national averages), Obama would be expected to win by roughly 8 points. But now, the same district would be expected to go to Clinton by 8 points. Conversely, however, Obama would be expected to win a Democratic-leaning district that he might have lost before.

This helps to explain how polling in New Jersey and California, two states with fairly liberal-leaning electorates, now suggests that Obama might have won those states. But it also proved to be helpful in Oregon. My modeling was consistently showing Oregon to be a toss-up state -- leaning only slightly to Obama. And if Oregon had voted back in February, maybe it would have been a toss-up. It might be noted that in Washington's beauty contest primary (which the model does not use directly in its estimates), Obama beat Clinton by just 3 points. And Washington should be a couple of points stronger for Obama than Oregon, as it is wealthier and has a somewhat larger black population.

But now, that isn't how Oregon is likely to vote. Clinton smartly recognized that the states that were scheduled to vote late in the primary process were moderate or conservative-leaning states. As such, she has moved somewhat to Obama's right. That's going to work to her benefit in places like Kentucky, but she's liable to pay a price for it in the one Kerry state that remained on the calender, which is Oregon. Tack on a couple of points for the fact that Obama has engaged the state more actively, and he could be looking at a double digit margin.

* - *

Apart from recognizing this time trend, I made a few additional tweaks to my model. Fundraising is now tracked at the Congressional District level, although as it turns out that you do best with a combination of local and statewide numbers. There is also a relationship between the fundraising numbers and a state's ideology; the more liberal a state's electorate, the more important the fundraising numbers tend to be. We have accounted for this effect as well.

I have also tracked candidate visits at the CD level; a visit may be split between two or more districts
if the city a candidate visit straddles more than one Congressional District. As it turns out, a visit to a CD does not appear to have any strong effect on the way that the vote is divided up in that district; it only affects things in the state as a whole. However, candidate visits do appear to have a localized effect on turnout. If you think about a typical campaign event, it is probably designed more to generate enthusiasm among a candidate's supporters than to persuade undecideds, who aren't as likely to attend the event in the first place. This finding would be consistent with that characterization. You draw your supporters to the event itself, hoping to make sure that they turn out. But thereafter, you're mostly benefiting from the earned media, which is not invaluable, whose effects tend to be more dispersed across the state.

It is interesting, by the way, to see the different ways that the candidates tend to plan out the geography of their events. Obama is more inclined to double- or triple up in a particularly important Congressional District, whereas Clinton tends to blanket her states more evenly.

Finally, as Oregon has a decent number of Hispanic voters, we are accounting for that variable as well. Holding everything else like income levels constant, Hispanics perform worse for Obama than what we call our white Anglo-Saxons, but marginally better for him than certain other types of "ethnic" whites. When you see the large margins that Clinton rung up in South Texas, keep in mind that they were very similar to her numbers in West Virginia. Ethnically, the two areas are very different, but economically they are quite similar.


*-*

Let me run through Oregon's Congressional Districts:



OR-1 (Northwest / Beaverton).
We name the first district, tucked away in Oregon's Northwest corner, after the city of Beaverton, but it also includes portions of Portland. Either way, it's solid Obama country. OR-1 is Oregon's wealthiest and most educated district, its population is relatively young, and it's bohemian and gay-friendly -- all of which are favorable markers for Obama. Still, it isn't especially extreme in most of these departments as compared to the national averages, whereas its 1.3 percent African-American population is exceptionally low. It's not out of the question that Obama could get a 5-2 delegate split here, but our model thinks he'll fall a few votes short. Projection: Obama 62.1, Clinton 37.9; Obama 4-3 Delegate Win.

OR-2 (East / Bend). The second district, making up the eastern three-quarters of Oregon's land mass but only a fifth of its population, is among the most difficult in the country to characterize. It is the third-whitest district in the entire nation, it is very much blue collar, and it also has a high senior population. But Clinton has not fundraised at all well in OR-2, and it has a high veteran population, which is one of Obama's hidden bases of support. The model thinks that, had the Oregon primary been held on Super Tuesday, this district would have gone to Obama by several points. But with Clinton now overperforming in conservative-leaning districts, it sees it as a toss-up, very slightly leaning Clinton. With that said, I wouldn't be surprised to see a result as lopsided as 58/42 for either candidate in this district. Projection: Clinton 50.2, Obama 49.8; Clinton 3-2 Delegate Win.

OR-3 (North / Portland). This is the district most commonly associated with Portland, and also with Oregon's reputation for progressive politics -- it has, for instance, the highest proportion of gay households of any district not associated with a top-15 metropolitan area. In other respects, it should be slightly less favorable to Obama than OR-1; its income levels are only average, for instance. But as this is the most liberal district in the state, there are about 75,000 reasons to think he might overperform here and get to the 61.1 percent he'd need to grab a sixth delegate. Projection: Obama 61.5, Clinton 38.5; Obama 6-3 Delegate Win.

OR-4 (Southwest / Eugene). Obama has spent a lot of time in this district, and that makes a lot of sense because he'll need to turn out the student vote at University of Oregon in Eugene in order to win it and take a majority of delegates. If not for Eugene, OR-4 would be essentially indistinguishable from OR-2, although it's more urban and does not have OR-2's Republican lean. We think Obama will just squeak by. Projection: Obama 51.7, Clinton 48.3; Obama 4-3 Delegate Win.

OR-5 (WNW / Salem). Congressional Districts containing state capitals are not infrequently swing districts, and Salem's OR-5 is no exception. It's a combination of rural Oregon and urban Oregon and its demographics are similar to the state averages, producing results that should closely track Oregon as a whole. To the extent that OR-5 distinguishes itself, it tips slightly younger and wealthier than the rest of the state, but Obama remains a slight underdog to break the 3-3 delegate deadlock. Projection: Obama 56.9, Clinton 43.1; 3-3 Delegate Split.



The model is projecting an Obama margin of approximately 13 points on turnout of about 570,000 voters, which would represent around 70 percent of registered Democrats in the state. Because Oregon's mail balloting has produced relatively strong turnouts in previous elections, this turnout figure may be slightly low, but it is difficult to conceive of turnout of more than about 650,000 in this closed primary. I have, by the way, switched back to estimating turnout as a function of the age-eligible population in the district rather than the number of Kerry voters, which turns out to be the more reliable way to do it.

Unlike some previous contests, Oregon is a delegate-watcher's dream. A delegate could easily change hands in all five of its Congressional Districts, as well as a couple at the statewide level. Obama will need to win Oregon by 8.3 points to pick up an extra statewide delegate, and 16.7 points to pick up a second. Overall, however, we have him coming up just short on a couple of counts and finishing with 29 delegates to Clinton's 23.

Keep in mind that about 4-5 points of our projected margin stems from the fact that Obama has spent more time on the ground in Oregon. Without that campaign activity, the state looked to be just close enough that Clinton must have faced a tough decision about whether or not to campaign seriously there. It's likely, however, Clinton effectively decided her fate when she decided to move to the political center; an issue like the gas tax moratorium plays quite badly in Oregon. Her goal was to have a strong showing in North Carolina and Indiana, perhaps even running the table in every state but Oregon. But Oregon was probably going to have to be sacrificed to enable that strategy.

Just wondering, how do you resolve recent polling from ARG and Suffolk showing the race within 5%? This is after PPP and SUSA showed 10-12% pre-WV... in those polls as well, it was seen that among those who have voted already, it was a tie, but among those yet to vote, it wasn't. I really hope the Portland Rally yesterday will drive home the need of Obama supporters to still vote to make this thing official.

Also wondering, how does one Exit poll voting by mail?

Obama should win Oregon by around 15-20 points and Clinton to win KY by 20 - 30 points.

jonlorusso said...

I think you have a typo in the 2nd to last graf:

Oregon will need to win Oregon by 8.3 points to pick up an extra statewide delegate, and 16.7 points to pick up a second.

I think that should be Obama will need to win...

As usual, great post!

Kubla:

There are several issues with that Suffolk poll.

#1. Only one-third of their sample had already voted. Among those voters, Obama led Clinton by 8 points. But by this point, somewhere north of 2/3rds of Oregonians should have already mailed in their ballots.

#2. There are a lot of refusals in their survey. About 6 percent of their sample, including 13 percent of people who have already voted, are coded as "refused". I can understand if people who have already voted don't want to discuss their ballot with a pollster; some people are very sensitive about the notion of a secret ballot. But it's a little bit unusual to include them in your survey.

3. Their cross-tabs are a little odd. They have nearly half the state described as 'Southwest', when that's not where the major population centers are. They also have just 12 percent of the electorate as age 18-35, whereas SurveyUSA has the same number at 19 percent (somewhere in the 15-20 percent range looks right to me based on the exit polling in other recent primaries).

I would not give a whole lot of weight to this poll. The other errors are probably forgivable, but there's no way that just 1/3 of the state had voted when they ran these numbers over the weekend.

As for the ARG poll -- well, you know.

There won't be any exit polling in Oregon...we'll be in the dark.

One big drawback of their voting method...

About 'student districts.' In some states, e.g., Michigan, students' voting residence by default is their home town (parents' or permanent address) and not their college town address, unless they've taken the trouble to change their registration and keep it up to date as they relocate each year. They may vote absentee in their home district, of course, but they have to plan ahead or in the case of many students in MI return to their home town to vote. The effect of this is to "suppress" the student vote in the college towns and keep some otherwise liberal districts voting more conservative.

I have no idea what the rules are in Oregon but wonder whether this is a factor there. Also worth considering is that at this date a lot of colleges and universities have closed down for the academic year, so students may well be voting "at home."

The revolutionary thing is not that you introduce ideology; it's that you introduce dynamics.

What you're saying is that the race was demographically stable but ideologically dynamic. I think this is wrong.

There are two ways this could be.

One is if the ideological positions are evenly distributed across the demographics. I am pretty sure this is demonstrably false.

The other is that the ideological dynamics have been masked so far because their demographic distribution so far ended up with the various trends canceling each other out. However - so the argument would continue - Oregon has a different demographic make-up and for this reason now, for the first time, the dynamic ideology is going to manifest itself - the algebra is going to work out as an Obama plus this time though it worked out as an Obama/Clinton zero so far. You did not really present an argument for this and I doubt this myself. But is this your position Poblano? You really have to present the algebra that supports this.

The practical alternatives to "static demography, stable ideology" are two: either (1) both are stable, or (2) both are dynamic.

(1) Perhaps one should not assume any ideological dynamics. In fact, the question naturally arises from your analysis: if Clinton's veer to the right did not work in her favor in NC/IN, why should it harm her in OR? Then one should predict a narrow OR result.

(2) Or perhaps the underlying reality of this race is much more complex - subtle dynamics at work with demographics (different demographic groups did change their voting preferences, somewhat, over time; also, different demographic groups changed their propensity to turn out to vote, over time) as well as ideology (different ideological groups changing over time as above), the combination of all the subtle shifts tending to cancel each other out *on the whole*.

But perhaps somewhat less canceling out this time (primarily, one would think, because Clinton's slight improvement with low-income Whites was partly racially motivated and for this reason would be more marked in the East? Thus the demographic shift, this time, would not cancel out the ideological shift). Then one could expect a somewhat better result for Obama.

Two theories: that the race was rigidly stable; that the race was dynamic, in a complex way, with several trends canceling each other. For once, we have something like a deciding experiment tomorrow!

Jerome Armstrong said...

Given that 582K have already voted as of May 15th, it looks like you're underprojecting the vote again. The total will be about 700K.

jr1886 said...

I love your work Poblano and i have to keep refreshing from time to time to see if theres anything new.

I think, as you admitted, your turnout might be at the low end. I can see a 700,000.

jerome armstrong said...

Maybe not, the 700k projection is total, the above in the post is referring to the Dem voters.

jr1886 said...

SurveyUSA has new numbers and it shows a 13% pts victory for Obama too. Coincidence?

I think it's going to be a 15% victory for Obama.

MetaData said...

Is there a pile-on effect as we get toward the end of the primary, and people start to see Obama as inevitable?

Also, I think voters are relatively stable in terms of their own ideology, but if Clinton has shifted her message to the right of Obama, we might be talking about changing perceptions of the candidates' ideologies.

another Mike said...

FWIW, SUSA has just come out with their final Oregon poll, showing Obama ahead 55-42, the same 13 point margin Poblano predicts. Perhaps they held off publishing final results until they could check them against your predictions Poblano?

jr1886 said...

Funny, I had the same thought too Mike. However, I doubted they would do that. The president of SurveyUSA, Jay Leve, is a very honest guy.

Anonymous said...

I think your model could easily be surprised by Oregon, because while there is certainly an urban/rural split in the overall population, one thing that is different about Oregon is that rural Democrats and urban Democrats tend to be (anecdotally) a lot more similar than in other states. I wouldn't be shocked to see results in Districts 2 and 4 end up closer to results in Portland than your model suggests. I might note that there is actual data to back up my bloviating: the SUSA polls show pretty similar preferences for both the Portland metro and the rest of the state. The results will be interesting!

A note to Anon above: since Oregon is vote by mail, many college kids are registered at their parents home address. All college kids have to do is nag their parents to forward their ballots to their colleges, whether they are going to college in Oregon or anywhere else in the country. It's a heck of lot easier than figuring out how to register and finding the polling place at school. It also means that we might not see the increased support in University towns that we have in other states, simply because the college votes are being counted in the students' hometowns.

Anonymous said...

The people suggesting that SurveyUSA waited to see 538's projections before releasing their poll (and some even implied that they copied Polbano's results) are insane.

First, to question the integrity of a polling company with literally no evidence is absurd.

Second, SurveyUSA sent the results to the sponsor/client and the media before Poblano's wonderful and detailed projections. You live in a fairy tale world if you think the second that you get access to poll results is the time a poll is first released.

538/poblano said...

Jerome,

Yeah, those figures from the Board of Elections include Republican voters (and maybe even some non-partisan voters who I think get a ballot). That tripped me up before too.

Anonymous said...

Hi Poblano,

Interesting work as always. I think your model might still be underestimating turnout. Is it possible that the longer this race has gone on, and the more media exposure each candidate has received, the higher the turnout becomes? Recent contests all seem to be on the high end of turnout.

Will you be posting your county-by-county scorecards like you did for NC and IN? It was fun to compare actual returns against those scorecards.

torridjoe said...

Once again, those ballot turn-in numbers are suspect. By midday of the first day of polling, the SoS reported a 40% Democratic turnout. 77% just seems way too high.

I wouldn't necessarily discount the rest of it, but I wouldn't take the "already voted" angle seriously.

538/poblano said...

Anon,

Clinton actually has been outperforming her projections by just the slightest bit. She beat the model by 2-3 points in North Carolina, and 1-2 points in each of West Virginia and Pennsylvania. Those aren't huge numbers by any means, but they're a little something.

538/poblano said...

Other anon,

The turnout model now accounts for the fact that turnout has tended to increase over the course of the primaries. There's definitely a time trend there.

jr1886 said...

Anonymous,
I think you should chill out a bit. It was all a joke and no one is implying that SurveyUSA copied Poblano's numbers.


PPP have new numbers out and they have Obama with a 19% pts victory.

Just asking: what in the world is wrong with ARG and Suffolk polls??

Anonymous said...

Anon above (with the long methodological comment). I'm confused. Are you referring to ideological dynamics over time or dynamics across venues (states).

You wrote: What you're saying is that the race was demographically stable but ideologically dynamic. I think this is wrong.

There are two ways this could be.

One is if the ideological positions are evenly distributed across the demographics. I am pretty sure this is demonstrably false.


I don't think he has to assume that ideological positions are evenly distributed across the demographics, or even that they were somehow masked. He can assume that they are to some degree malleable for any demographic group, not fixed either for all time or over space. In previous models he assumed perhaps that the central tendency for any given demographic group (say white working class) was fairly stable in the states he had used to "train" his model; and that has proved to be a fairly decent assumption at least after he had enough prior primary elections to reduce the random error owing to a small N.

In Oregon he seems to say that for a given demographic group the Dem primary voters are likely to be more liberal than in other states. Without applying a spatial model, but making some observations from the campaigns of the two candidates (Clinton playing to the "right" of Obama, especially since PA), he expected Obama to hit the sweet spot of the Oregon liberal Dems.

Furthermore, unlike in WV where a lot of "presidential Republicans" vote in the Democratic primary, or in Indiana or Texas where there may have been some Republican identifiers who crossed over to vote for Clinton, that liberal Dem "sweet spot" isn't going to be corrupted by non-Democrats voting in the Oregon Democratic primary.

At least that's how I see it. Perhaps you could elaborate or show where I'm wrong. Thanks.

You are not one to show off are you? In the last four primaries, you got the delegates right in two and were wrong by only one delegate in the other two primaries. Wow!

Josh Putnam said...

Poblano,
I'm curious about this 16 point shift in Republican districts favoring Obama at first and now Clinton: Were you controlling for whether the contest was a primary or caucus in those calculations? I sound like someone from the Clinton camp here questioning the worth of caucuses, but how many of those R+10 districts are in caucus states?

Hah! Survey USA's latest Oregon polls match your prediction! Well done!

To 12:08, this is the long methodological comment anonymous answering.

There is no problem with the idea of introducing a new variable. Poblano I think did change his variables somewhat from one set of projections to the next.

And the "ideology/demographics" is actually a slightly confusing notion. "Ideology" as defined here *is* a demographic criterion (it matches certain past fixed surveys, not a dynamic set of positions).

What's interesting is that Poblano for the first time assumes a dynamic analysis: certain variables have different impacts with *time*. This is difficult to square with the fact that the race was demonstrably stable with another set of variables. If you give a thought to the algebra of this you'll see why. And it then definitely assumes that this newly considered "ideology" variables is somehow supposed to have been masked in the past.

KAP said...

Way back on Super Tuesday, when the Obama campaign leaked their spreadsheet, they were predicting a delegate split of 28-24 on the basis of a 5% win. So I don't think there are going to be many surprises except the strength of his victory now that the nomination is assured.

Michael said...

Senator Obama won the WA primary by 5.55%, with King County's turnout well below the average.

A good number of those ballots were mailed on or before February 5, which is why Romney had 20% on election night, but only 16% in the final result.

The students not on campus comment doesn't appply in Oregon, even if it were an issue in a vote-by-mail state. Oregon schools are on the quarter system and arent't over until early June.

The difference between Oregon and Kentucky and West Virginia? Ummm... one's not in the South? (While Oregon will go for either Clinton or Obama this fall, KY and WV will go McCain no matter what. Neither a black man nor a white woman will do well in the general in the South.)

As for, say, Ohio, PA, and Indiana (which she barely won after being massively ahead most of the primary season), look to the mayors, as Kos says. PA's mayors and most of the PA political establishment (including Philly's mayor and PA's governor) are very pro-Clinton. Ohio and Indiana had similar dynamics.

Re: college students in Oregon, none have gone home yet, that I know of. They end the year in late May or early June.

Re: OR 4, I've lived in Oregon since 1980, 8 years of it in Eugene. I'm thinking OR 4 will be much more in Obama's camp than you think--Eugene is known all over the state for its liberal leanings, and not just on the UO campus. Hillary's shift to the middle will have alienated them.

FWIW, part of the dynamic all over the state is a pretty fierce independent streak.

Rasmus said...

I also think that Oregon should be well within double-digits. Maybe even 20 points.

Anonymous said...

I think you underestimate the 04/Eugene vote for Obama. These voters have little to no affiliation to or sentimentality for the Clintons. Eugene is a radical center of politics. I think Clinton will totally tank here. I also think that 02 voters will go to Obama much more than you have projected. There just isn't the same sort of knee-jerk racism as in WV or TN.
