I'd like to add that Alito would quite possibly not have been confirmed were this not an election year. The Democrats have hopes of re-capturing part or all of the Congress because of perceived weakness in the performance of the Bush presidency. They know that Americans are essentially conservative on the question of judges and do not want to chance making the court a midterm election issue.
Thus, we have the compromise. Hold a dog and pony filibuster show that allows the senators from safely liberal states and those who wish to audition for the primaries in 2008 to prove their love to the Dean/Moore/Move-On faction. Then, hold the real vote, let a few vulnerable Dems vote for Alito while the rest of the caucus votes no, and go back to "Bush lied, people died."
There's the script. Get ready.
