Ann Coulter has taken her incredibly dark, reactionary comedy to new heights with this 9/11 widows bashing routine. She's abandoned all pretense of genuine outrage and leapt into the realm of self parody. She's Stephen Colbert without the knowing wink.
Andrew Sullivan nails Coulter's schtick perfectly:
She's not a social or political commentator. She's a drag queen impersonating a fascist. I don't even begin to believe she actually believes this stuff. It's post-modern performance-art.
