It seems to me Trump worships the idea of “the deal” too much. He praised Mitch McConnell a few days back. Trump will make a deal with the GOPe. He wants to show everyone what Trump can do. He won’t be able to do much without them.
I don’t know for sure what motivates Trump. I like that he has a history of saying what he wants without fear whether or not it is politically correct. I like that he is the only candidate that the English Parliament debated banning from their country. You can’t get an endorsement much better than that.
