This will be my final response to you. How is it that Reagan managed to work with a Congress that was 272 to 158 when he was first elected? In fact his entire presidency the House was in Democratic hands. Tip O'Neil was Speaker. Yet somehow, Reagan got a good chunk of his agenda through. Somehow Reagan managed to work with what he had to work.
Did Trump do this? Or, was it because he wasn't part of the swamp that he couldn't? That's the real question. Not whether or not the Pubics supported him, because we known dang good and well many of them didn't, and not until after the first year were many "on his wagon." No Republican wants to cut spending, and that's why I cannot support the party as a blanket statement.
I'm not a Trump hater; I just think he made some critical errors. Which, BTW, so did Reagan. All Presidents make errors; that's part of the job. However, If one cannot look at the bad along with the good, then they are no better than the very folks they criticize. But without a doubt Trump surrounded himself, due most likely to his inexperience in politics and not understanding how deep the swamp was, with bad people. I'll be the first to say Trump was a blessing to The USA and I firmly believe he loves this country; but he did some things that were not so smart.
