Kate made this point to me a while back: In this election we have seen women vote for a woman, blacks vote for a black man, Mormons vote for a Mormon, and evangelicals vote for an evangelical. Even the strong Hispanic support for McCain in Florida seems as much a matter of group solidarity as of individual interest. You could say it’s the way of the world. But the level of group voting in this election has been a lot higher than in any recent election I can think of, and it has been decisive multiple times.
