I guess that sort of depends how you define "racist". If that definition includes any politically incorrect reference to race (which has become the standard definition), then he is most certainly racist. If you consider more restrictive definitions, it's not as clear.
His "clean and articulate" remark was surely meant to be a compliment, but came off sounding much worse than it really was. It does give some insight into the way his brain works, however.
There's no question he says stupid things on a regular basis. I look forward to more of them as the campaign unfolds.
I think he’s like Imus. An all around loser.
