> the entire party aggressively supporting him and everything he does.

That's untrue.

If you do some homework you will see Republican politicians and the Supreme Court disagreeing on a number of issues. Amongst Republican voters, his approval rating has been sliding and is now below 80% in most polls.

They passed one major piece of legislation since he took office and it was loaded with pork to get everyone onboard. I wouldn't call that aggressive. The Right is very fractured right now.
