Ann Coulter stumbles again

I heard with some surprise the outrage over Ann Coulter's latest remarks - a pathetic joke about John Edwards (she said she would talk about him except you have to go to rehab if you call someone a faggot, which is a reference to Grey's Anatomy star Isaiah Washington). I have to give her credit for managing to get in digs at two people at once, but I can't see why anyone bothers to get upset at anything she says - she has absolutely no credibility as a political commentator anymore, and she appeals to only the most rabid and foolish extremists. Pointing out that Ann Coulter said something outrageous is rather like saying the sky is blue.
