Florida: 19 percent of those who backed Clinton in the primaries now support McCain.
Ohio: 25 percent of those who backed Clinton in the primaries now support McCain.
Pennsylvania: 24 percent of the voters who supported Clinton in the primaries now back McCain.
Those are higher percentages than I would have expected. I'd like to see how the numbers break down. Surely some of these voters were convinced by the Clinton campaign that Obama is all flash and no substance, some are working through resentment at Obama for taking away Clinton's golden ring, and others are driven by dissatisfaction with Obama on trade, taxes, or whatnot. But how many Democratic primary voters just aren't going to vote for a black man? I'm inclined to think that the number is fairly significant, though I'd also be inclined to think that most of those voters would glom onto some other issue rather than admitting -- even to themselves -- that race plays a role in their voting behavior.
