I hate to say I'm not surprised by the poll, but I would suspect that many Dems who won't vote for Obama based on his race are probably part of the group we used to call the Reagan Democrats: generally blue collar workers (from the NE industrial states) who are socially conservative.

I'm not indicting all social conservatives, but they are a great deal more likely to be racist than people who are either liberal, or middle of the road regarding social issues.
