Hey Xong.
I hear the guy closer to the mike at 1:36 say "Traitor...go home", but at 1:33 I hear someone further away use the n-word.
I'd have to agree with some of the other posters which claim "traitor" is the more pronounced hurled epithet.
But I think you're correct that "nigger" is a possibility at 1:33. Then again, so is "neener". Or "wig herd". I wasn't there, so all I can say is "nigger" may be what was said at 1:33, or at any/all other portion(s) of that teaparty protest. However, I find it not
too difficult to accept that the word was indeed flying about at that particular event, especially considering both the multiple eyewitness accounts, as well as the teabaggers' reputation for douchebaggery.
Have a good one.
