Matthew Dowd's criticism

Matthew Dowd, who helped G.W. Bush get elected as a top strategist in 2000 and 2004, came out against the president on the front page of The New York Times. He's become so disillusioned with the president, and especially the war (which his son is fighting in), and concerned that the president is out of touch. From the story:

Mr. Dowd, 45, said he hoped in part that by coming forward he would be able to get a message through to a presidential inner sanctum that he views as increasingly isolated. But, he said, he holds out no great hope. He acknowledges that he has not had a conversation with the president.

I don't believe this, actually. I believe that he's feeling horribly guilty over what he did, and feels compelled to atone in some way. Hard to blame him, but there is something weird about going to the New York Times to denounce your former boss that way. Andrew Sullivan likens it to David Kuo's turning on the White House, in that both former Bushies' apostasy takes the form of seeking spiritual atonement. David says he doesn't speak out against the administration now out of a sense of anger, but sadness.

Dowd's story made me think about what was my personal tipping point on Bush -- the thing that made me turn against him. It was Katrina, specifically "Heck of a job, Brownie," but the Harriet Miers for SCOTUS business followed quickly on that. After that fall, I'd had absolutely enough. If you're a reader who used to back Bush, but no longer does, what was your tipping point with this administration?
