The republican majority during the first two years of his presidency stalled on enacting any of his policy- and now they are much more vocally opposed to Trump- as if they always hadn't been. He's a populist candidate- but he's not at all popular with the actual politicians, who are currently the actual infrastructure of the party. His hold on the party is tenuous at best- mostly because the people that oppose him when it comes to voting will still happily campaign with him and win based on his supporters. The recent soft blacklisting of Trump support from Fox is also going to take out a chunk of his base that will continue to vote for the color red.
