Probably not similar on the "Is Obama secretly a Muslim?" question, but as Democrats they're less likely to believe negative things about their party head.

My point is that there are many, many racist Democrats in the country, and if you don't think so you just haven't gotten around very much.

Yes, in America if you're bigoted against blacks, you probably vote Republican. If you're bigoted against whites, you probably vote Democratic. If you're bigoted against Muslims, you probably vote Republican. If you're bigoted against all religious people, well, you probably vote Democratic.

It's probably a function of the area I live in, but every antisemite I've run into in the past few years has seemed very left-wing. (I say 'seemed' because I like to keep a healthy distance from antisemites. I'm only going by shouting and signage.)

While we're on the topic, the political leanings of bigots are fluid. A generation or two ago, if you were bigoted against blacks, you probably voted Democratic.
