I think Michael Kinsley nailed it with this one:
"In four years, this small man had two historic opportunities to reach for greatness, to lead this country to a new and better place, and he passed up both. The first was when the Democrats patriotically bowed to a Supreme Court decision they believed to be wrong, if not corrupt, so that the U.S. could avoid a further constitutional crisis. What a moment for bipartisanship! Maybe put more than a token Democrat in the Cabinet? Not a chance.
George W. Bush's second opportunity came on Sept. 11, 2001. Past grievances suddenly seemed petty, current disagreements seemed irrelevant, and, even among Bush's opponents, desperate hope replaced sullen doubts that our nation's leader would be up to the task. Bush got this gift from the opposition—the suspension of dislike and disbelief—without doing anything to deserve it. He could have asked for and got anything he wanted in the weeks and months after 9/11. And he decided to invade Iraq.
For once, George W. Bush was tested. And he flunked. "
It's been a dreadful performance, a train wreck of an administration, and nobody to blame but themselves. Oh, yes, and Clinton. Dubya hasn't forgotten his A-B-C's -- Always Blame Clinton.
