Via Matt. Turns out that among McCain's former Hillary supporter is some idiot who insists that Thomas Jefferson never had relations with that woman, Sally Hemmings. There's a great comment on Matt's page about this sort of thing backfires and that, in the real world, Dogs aren't the only ones who hear dog-whistles. I don't think McCain is a racist. But this is like the street. You hang out on the corner long enough and you will end up in the company of drug-dealers. Ditto for the GOP, and McCain Democrats. Move among them enough, and you will find yourself in the company of racists. That said, Kathy G made a great point in comments today. A lot of these "Clinton supporters" could well be plants.
