@maxdancona,
My opinion is that Trump doesn't feel pressure from the Senate at all. That is why McConnell is out of the game. He used to able to count on Ryan to get a simple majority and pass whatever he sent them, that's out now. If McConnell were willing to override a Trump veto, then he would have some clout, but he's said he is not willing to put anything to a vote that the President doesn't support, so he's got nothing. Likewise, moderate Republicans don't have the votes to replace McConnell so he can ignore their protests. I don't think the Senate has a "discharge petition" that can override leadership, so if McConnell doesn't want to vote on something, it's not going to get a vote.
