Fifty-one Republicans and one Democrat Ben Nelson of Nebraska support Alito. . . . Four Republicans, 23 Democrats and independent Sen. Jim Jeffords of Vermont were still publicly undecided Wednesday or refused to say how they would vote on Alito's nomination.
For the math challenged, that means 20 Democratic Senators have said that they will vote against Alito.
At this point, any stance other than "I will filibuster Alito", is an assent to his confirmation. Republicans need to secure support from eight of the twenty-eight Senators who have not announced their positions to prevent that from being possible. I don't think that this will happen. Democrats can stop Alito, a nomination that they overwhelmingly oppose, if they have the political will to do so. It is unclear if they actually do. We will have a much better idea a week from now.
