Sorry I cant agree with your assesment.
I have never bought into the argument that the democrats could successfully filibuster a Supreme Court nominee. Its one thing to filibuster an Appeals Court nominee when there are literally hundreds and most people arent even paying attention. A SCOTUS nominee is an entirely different matter. There are only nine its its a highly visible event. Particularly if that nominee is clearly and visibly qualified and capable. If they go through the hearings and do a good job the public will insist on an up or down vote.
Besides which EVEN IF THEY COULD the pressure shold be on them to carry it off. We shouldnt refuse to step up to the plate and fight that fight just because we are afraid we MIGHT not win.
OK, fine. I think you underestimate the audacity of Democrats and their campaign managers in the MSM. You also I think underestimate the fear of soccer moms over their own definitions of "a real conservative". But I expect we'll soon see.
