I can understand sucking up to Trump while he was president - like it or not, he really was the president, and had demonstrated a willingness to veto legislation over trivialities, and to use the Bully Pulpit as an actual bully. When the voters throw you a curve ball like that, you've got to deal with it.
But now that he's lost, it makes no sense to keep sucking up to him. Go along to get along when you have to, but once the wicked witch is dead, you sing the goddamned "ding dong the wicked witch is dead!" song.
