Trump is finally realizing his mistake of coming out and throwing insults at Congress and pushing them away right out of the gate. He now realizes the hell he'll face if the Dems win.
That analysis goes both ways.
Trump obviously is a bit of a loose cannon, and that's not always good. He pissed off some folks whose help he needed.
But some in Congress are starting to realize how badly
they needed a kick in ass from someone willing to hit the beach hard and start trying to retake lost ground.
It was the passivity and lack of willingness to engage that cause the "Trump problem" for the GOP in the first place. But many in Congress are now rallying around him because they realize how badly they needed someone willing to lead a real fight. The GOP actually is more unified, and more in sync with it's grassroots, than it has been in a long time.
