Oh, my sweet summer child. I don't pretend to understand politics, but some parts of the picture are coming into focus. What I think I know is that we've got a tail wagging the dog wagging the tail situation going on here. Nothing happens unless it is politically popular enough to happen. Except that it's often hard to tell, so mostly nothing happens, just in case.
I was listening to a political radio program earlier today and I think the host explained a part of this very well. There is a large swath of Republicans who find Trump to be unsavory, but in their view he is far better than the alternative. This is mostly based on their policy views, not necessarily on their views of the character or ability of the candidates. So, for example, a serial rapist, say, would still get Republican votes as long as he was for closed borders. The host pointed out the major flaw in this approach, which is that voters who do this are putting party and policy above country. It's especially true when there are not only huge character flaws, but actual attempts to overturn a lawful and valid election. We're talking real, live attacks on democracy. Even that is not enough to get people to vote for someone with a different view of guns, abortion and the border. It's absolutely insane.
