Snowe, Chaffey and Collins might be a questionmark right now. From what I've read this morning, Sen Specter seems to be supporting Alito's nomination.
From what I see from the gang of 7 Warner,McCain,Graham and Specter are pretty solidly onboard. I think Collins and Snowe who voted for Roberts might have a real hard time saying no to this nomination. Dem Conrad might vote for him because he has a tough reelection battle looming in heavy Pubbie North Dakota. I don't know what to think about Lancelot Linc.
