I'd say I agree with about 75% of the things Keith Olbermann says. And yet, I find him sanctimonious and annoying pretty much 98% of the time. His unbearable smugness is actually HURTING his cause.
Bill Maher is kind of the same way. I WANT to get behind these guys, because they are on the right side and have large platforms, but I just can't do it because I kind of want to just smack them in the face. It's on my nerves lately.
