So far Trump 2.0 has done exactly what he promised he would, and his supporters are quite happy. If his actions don't lead to the outcomes he promised that may change, as long as someone else who understands the needs can offer an alternative.
I think we did that experiment in November, and it doesn’t support your assertion that people suddenly turn into rational performance evaluators after the election (or in this case an entire first term).
In any case, this time around the likelihood is Trump will be long dead (of natural causes, I mean) before the impact of this election is realized. The change happening right now is generational in scale. The voters’ children will be reading this chapter in their history book and asking what on earth they were thinking.
