Having complained here about talk shows with near-scripted interviews, I offer an exception. Jon Stewart usually asks his guests questions they don't expect…and not in a "gotcha" manner. Sometimes, when he has a serious Conservative on, there's actually a real back-and-forth where two grown people talk like grown-ups and don't demagogue.
I link you here to the extended version of the interview he did last night on his program with former Senator Jim DeMint, who is quite the poster boy for the Tea Party movement, although I don't think that group was mentioned. The shorter version that aired on The Daily Show wasn't much but the two men spoke for more than a half hour and you might find the whole thing worth your time.
