President Trump will get far more Dems, in Congress, to help him pass many of the things he wants, than you imagine and yes, many GOPers will give him a hard time. It happened under Reagan and other GOP presidents. Factual history is your friend.

I once had to wrestle a guy in college that was two weight classes above me. He told me he was going to separate my shoulder. I fractured his collar bone in the first period and walked off the mat with a win by injury default.
