When he was in office before, it was really just him, with the entire mainstream establishment of both major parties working to undermine him. Thanks mostly to Steve Bannon, that's not really the case anymore. The populist takeover of the GOP grassroots has started to trickle up. If Trump gets back into office, he will have actual ideological allies in Congress willing to support his agenda. At the very least, that would mean the wall gets finished and a few more years of non-interventionist foreign policy, on top of a better economy.

Again, not perfect, but it should at least be a mild antidote to your apparent case of blackpill poisoning.
