Correct. Other than base pressure, I am still wondering just what animated the Dem strategy here.
I think it was to get Republicans to kill the filibuster for SCOTUS.
In 2013, they left cloture for SCOTUS alone because they were afraid that Republicans could stack the court with conservatives at some point. But when it became clear that they're going to block everybody anyway going forward as best they can, the filibuster would hinder Democrats' ability to appoint a liberal judge. So they would have to nuke themselves anyway at some point. Better to have the Republicans do it so as to avoid the political cost.
McConell was already telegraphing that Gorsuch would get through one way or another, so the filibuster had lost its effectiveness anyway. It might have been more effective politically if they waited until a liberal judge needed replacement to press the issue, but then again, we don't know if that will happen under Trump.
