…and the role of race:
I can easily imagine a white voter who would deny that race made him “much more likely” to support Obama or even that race was “an important factor”, but who was nonetheless delighted that an exceptionally talented black man had presented himself as a candidate for the presidency, who felt it was a good thing for the country, and who would want to support him other things equal. I bet most of the people I know fall into this category (and they’re not all partisan Democrats). None of them would say they voted for Obama because he’s black–a sentiment, of course, that would be insulting to the man. Nonetheless, I think they’d say, it’s great that he is.
Call it reverse racism if you must. (That label is one good reason, by the way, to suspect “underreporting of pro-black sentiment”. People would rather think of themselves as color-blind than prejudiced in either direction.) Whatever: I think that attitude is entirely justified. It’s not being captured in the studies I’ve seen. And if it’s as widespread as I’d guess it to be, it could easily be worth another 2 to 4 percent of the popular vote.
As I’ve often written, the fact that he was (half) black was the only reason I could see to vote for him. But other things weren’t equal, so I didn’t. And won’t.
