Trump's huge mistake was not bringing the nation back together again after his win, throwing chunks of red meat to his base, and basically shoving a sharp stick in the eye of those who didn't vote for him, making enemies with Shumer and Pelosi when he could have got a lot accomplished with their help. The Crime bill was proof that the Democrats wanted to work with Donald Trump. He could have easily fixed Obamacare (something the Republicans want too now), and passed an immigration Bill (That everyone wants) too had he not alienated the Democrats with his focus on destroying Obama's legacy and attacking the Free Press making them enemies as well.
Basically Trump caused every one of his own problems by trying to fight, what seemed like the entire world- BUT RUSSIA, TURKEY, and N. Korea! And so now he will be a one-term president. And it's not going to look pretty for him in the history books. And now the Senate is up for grabs and already starting to tilt in the direction of Democrat Control according to all the polls
You hit the nail on the head with Romney. It seems he is a potential president who can bring people together. And I know he is an honest man and with good intentions. He will be the Republican's best bet in 2024. He will be running against Biden's choice for VP.
I think after Trump has spiraled down crashed and burned, I look for Romney to have a larger role in the Senate and the Republicans will start to come back to him as they abandon Trump and just looking ahead at 2024.
But for Trump, turn out the lights, as his playhouse is about to come down hard.
