The Alito Filibuster

Is the Alito filibuster a good idea? I can see problems (mostly political), but the basic idea is a good one. I would even go so far as to say it's an excellent one. If Alito is, as liberals believe going to rubberstamp the conservative viewpoint of Scalio and Thomas, than the filibuster - though failed - puts in place the mechanism whereby Democrats did everything they reasonably could to stop this nomination. As the year goes on, and if Alito tows the line toward more loss of personal privacy, including abortion rights; we will look back on this attempted filibuster as a watershed moment in the growing of the Democratic spine.
