Gary Holmes at Nielsen writes me with the following:
Nielsen just released the ratings for last night's Biden/Palin debate. This is for the 55 local markets where Nielsen has electronic meters.
* The overall rating was 45.0 -- much higher than the Obama/McCain debate, which had a rating of 31.6
* The Baltimore market had the largest TV audience, with a household rating of 59.1
* Los Angeles market had the lowest household rating: 34.4.
National ratings for Thursday night’s debate will be available from Nielsen Friday afternoon, and if these numbers hold up, this could be one of the most-watched debates ever.

So, based on the preliminary numbers, the ratings for the VP debate exceeded those of last Friday's presidential debate by 42%. Since the Obama-McCain debate drew an audience of about 52 million, that would translate into something like 70-75 million viewers for the VP debate. If it clears the 70 million hurdle once the ratings are finalized, it will become the first debate to do so since Reagan-Carter in 1980. It certainly will blow any other VP debate out of the water; the previous high was 56.7 million for Bush-Ferraro in 1984.
This certianly seems to attest to Sarah Palin's ability to draw a crowd -- even if some of those viewers may have watched in the hopes of seeing a train wreck. But also, it may be evidence that the first presidential debate was significantly hampered by having occurred on a Friday, and having had little promotional blast behind it (since the McCain campaign was threatening to pull out until the last minute). I would expect the final two presidential debates to be somewhere in the 60-80 million viewers range.
