This article in today's WAPO suggests that Richard Lugar will line up to be Bush's bitch on the Bolton nomination. That leaves Hagel and Chafee as the only two republican members of the Foreign Relations Committee that could spike the nomination.
I don't know who came up with the idea that Bolton is somehow going to reform the UN, but the White House is pushing that meme.
"A vote for John Bolton is a vote for reform at the United Nations," White House spokesman Scott McClellan said. "A vote against him is a vote for the status quo at the United Nations."
John Bolton can't seriously "reform" the UN. True reform must come from within and couldn't possibly be led by this jackass. Even Thomas Friedman knows that.
