Some TV network did some interviews with West Virginia voters at the time of their primary. The Daily Showpicked up on it (click link for video). Among the comments:
“I guess because he is another race. I’m sort of scared of theother race because we have so much conflict with them.”
“He’s Muslim and that has a lot to do with it.”
“I don’t like the Hussein thing. I’ve had enough of Hussein.”
The segment on this starts at 1:03 into the video, and the comments start at 1:45.
By the way, if you think Obama is Muslim, check out IsBarackObamaAMuslim.com. (Though it won’t comment on the separate question of why it matters).
