We’ve seen these kinds of charts before, but this one is especially good; it shows where Clinton and Obama got their support, when, and explains the why (as much as they can, anyway). Very interesting.

What’s interesting is how strongly Obama performed in urban areas, with three or four notable exceptions: largely Hispanic areas in the Southwest (like LA), South Florida, Appalachia, and Boston (?). Clinton’s showing in New York is not at all surprising, of course, and I expect that Obama will do just fine there in the general.
I think this map may play into the VP selection process. I hope to have some thoughts on that issue in the near future.
