Here's an absolutely horrifying (and not in a good way) clip from a documentary movie that is apparently making the rounds on its own "road show":
This woman was interviewed about the apparently then-upcoming 2004 election, and just listen to her justification as to why she is voting for Bush. As one YouTube reviewer of this clip said, "I threw up in my mouth a bit".
I don't know what the current status of this film is or where it can be seen -- a Google search doesn't come back with much. But from what I see from this small clip, this is definitely a film worth watching.
