Someone will crop up from the Dems in four years. Part of the reason that Bush was able to get re-elected was he was still in firm control of 9/11 paranoia which was still very new. He also did a decent job reaching out to try and bring Latinos into the GOP establishment. We’re through the other side of the looking glass, so unless there’s another even larger disaster in the US I can’t see Trump being competent enough to win a second time. That doesn’t mean that he won’t see the writing on the wall and go full blown fascist autocrat.
It’s only been a month and the ties to Russia will only deepen. As for the pandora’s box comment, the GOP opened that up decades ago. Trump is simply the latest evil to have walked out of it. Either the GOP schisms or I honestly don’t know if I can see the next decade not ending with some sort of civil conflict here.
