Senators who would vote no on a candidate aren't going to vote to go on recess just to enable the bypassing of their own vote.
The republican party needs this more than Trump. The GOP already has a big problems with their own voters. They need to prove that they can actually function as a legitimate political party and generate majorities and get results.
Trump will get control of The DOJ and FBI one way or the other. He will be The President after all.
Part of me hopes that they do try to play games and be obstructionists. The GOP will only destroy themselves and they will not be missed!
