Filibuster
I'm not sure this is true:
Most of the 44 Senate Democrats and one independent are expected to vote against Alito. But no Democrat has threatened a filibuster, largely because they do not appear to have the 41 votes that would be needed in the 100-member Senate to sustain such a procedural roadblock.
While a majority of Democrats may vote to oppose Alito, they are not filibustering because they are afraid of losing. Instead, they must feel they will end up on the losing end of the political battle on Alito.
America shows a great amount of indifference to Alito's approval. Were they strongly opposed, Democrats would filibuster whether victory was assured or not. Then they claim they did all they could to stop Alito, Republicans take the party line approval track, and the country elects a new majority to the House/Senate.
But that's not the story line at hand. And that, in turn, is why the Democrats won't filibuster Sam Alito.
Unless, of course, they come up with something to change public view in the next week.
