Kevin Drum has a few very good posts on Bush and on Abu Ghraib and links to some interesting commentary.
One of the writers he links to is Senator Lindsey Graham. I saw Graham on yesterday's Meet the Press, and was a bit of surprised. You may remember that Graham, while still a congressman, was a major player in the impeachment hearings and was a hard line Clinton antagonist. While still doing his best to be a good Republican soldier, Graham obviously hackled at Cheney's assertion that people should "get off of Rumsfeld's back", and seemed sincerely disturbed by the treatment of Iraqi prisoners.
All I could think watching this was, if Bush is losing the full support of this guy, things are going south really fast.
