Colin Powell has a chance to redeem some of the credibility he lost when he muled Bush's trumped-up Iraq disinformation to the UN. There are a lot of people coming forward bashing Bolton, but Powell is the only one with enough juice to spike the nomination.
Three republican Senators have contacted Powell for backround on Bolton. Bolton screwed Powell a couple of times when Powell was Secretary of State and I expect that Powell was frank about that when he responded to Chafee, Lugar, and Hagel. The question is whether any of these three has the balls to nix Bolton. Don't bring up Voinovich, he is too big of a bitch to stand up to Bush. Remember the tax cuts?
