No one should be under any illusions about the GOP sticking with Trump no matter what. Most Republicans in Congress are disgusted and mortified by the President. They continue to support him for one of two reasons (or both): fear of defeat in their next reelection due to Trump’s seemingly impenetrable control over his base, and the Faustian bargain that most of them cut with their consciences long ago. That is, they want to jam judges and legislation through while they have the power to do so.
