I think a Trump presidency would be neutered by a opposing Congress, but the predictions are that Republicans will have the majority in the House and Senate, in no small part due to gerrymandering. The Congress has radicalized sufficiently that many of the most extreme kinds of legislation stand a good chance of being passed. Trump will have the ability to choose the empty seat on the Supreme Court, which pay be passed favorable through a more extreme Senate than moderate. There is a risk that a second justice will need to be appointed in the next four years. The age of a couple of the justices is advanced. In a worst case scenario, not only does Roe v. Wade get reversed, but any number of other progressive decisions could be reversed. All of this is, of course, a worst case scenario, but it is fact not that far-fetched at all.
We have a strong dominionist movement in the country that has organized very effectively over the past twenty years. Pushing toward a theocracy of their making is something they have steadily pushed. At the local and state level, they have had many successes. Any one recall the power the Texas school board has had to shape the textbooks of the whole country in a nationalist, unscientific, unrealistic manner. Or Arizona forcing public schools not to teach Latino or African American studies.
Conservatives have pushed through Citizen’s United and its uglier descendants. They have deregulated the whole financial industry. They’ve restricted voting rights. They’ve chipped away at abortion rights until it is inaccessible in many states including sticking probes in women.
Then there’s this. Even if nothing extremist happened during his term, there is also the very idea that a man who speaks the words Trump does and carries himself with his temperament would be the leader of the country. I cannot stop thinking of my nieces and nephews growing up with that man as their example of leadership.
