John B.: I get the impression from the tone of your posts that you're completely misreading the situation on the Hill.
There is no way that Alito is going to be stopped. Unless they're really, really stupid, the Dems calling for a filibuster don't actually want a successful filibuster. They want to convince their far left base (which is really stupid) that they've done all they can. If the cloture vote fails, the judicial filibuster will be swiftly killed for good on a simple majority vote (the so-called nuclear option). It will represent a massive miscalculation by the Democrats. We should be hoping for that, not fearing it.
