Munchin & Heitkamp on board because all 51 Republicans will vote to confirm?
If McConnell were strategic about it, he would hold Flake, Collins and Murkowski out of the vote until just before the deadline, to try to force the Democrats to vote first. They won’t vote for Kavanaugh unless and until Republicans have the votes. At that point, they will be released. I would have those 3 wait til there were 10 second left to cast their votes. If they time it right, they might even get some Dems to miss the vote.
