Here, even when we finally have a truely bipartisan worked on and supported bill, Trump can't even sign it.
There was a time, right after the election, when I thought maybe, just maybe, Trump might be smart and at least pretend to share some policy ideas with Democrats and say...work with them to fix mistakes in the ACA. Or gun control. Or medicare for all, as he once publicly said he supports a more single payer universal style system.
But no, he proved more of a nut job who went the easy and ego fawning approach of going double down on his pandering to the lowest common denominator of his base, and demonizing Democrats instead of working with them.
His "Art of the Deal" is explained by someone I forget who, on Bill Maher's show, that applies in this situation. He has a terrible record for deal making because of a few things, one of which is that when it gets to the point where all sides are just about to sign, where the other side is finally okay with the terms of the deal, then it MUST mean that he could have gotten MORE out from the other side. That he must be being played for a sucker somehow if they are willing to sign. So he will quash deals based on that belief. Or re-open the negotiation, and maybe lose it that way.
