I don’t think that Trump’s negatives are of any importance to those who voted for him. The perception among his supporters is that he is doing exactly what he said he would do. He’s making government smaller (closing or downsizing a bunch of agencies), removing regulations, kicking out furiners, undoing things Obama did (esp. Obamacare), backing out of international agreements, lowering taxes (at least for some people), is very pro-Israel / anti-Palestine, and reducing environmental programs. His supporters have every reason to vote for him again, and I wouldn’t be at all surprised if he won even more comfortably next time. The democrats will need to run a very appealing candidate.
