This could just be a pep talk for the team, but McConnell is exceedingly good at getting votes to go the way he wants them to – when it’s a vote McConnell actually cares about.
I could be wrong but from what I know about McConnell has a Senate taskmaster, if Susan Collins or Lisa Murkowski is wavering, he knows about it. If Jeff Flake or Bob Corker is getting weak-kneed, he knows about it.
