I think the problem is that if you read what people say about why they voted for Trump, it becomes clear that an echo chamber is at least as salient to these voters as traditional Republican motivations.
I am unsurprised about the 2024 election and it's exactly what you'd imagine from a purely economic perspective.
The 2016 election, however, has been studied extensively, and it's clear that several aberrations (large contingent of Republican candidates, the first black president, Facebook, Comey) tipped things in a way that you wouldn't expect if voters are acting rationally.
So as someone who genuinely wishes to understand how people think about things, I don't know what's going on here. I can't tell what new lie will be pushed next week to distract us from the recently-disproven lie of last week. Were I outside all of this, I would have very little hope.
(edit: re sibling poster, Trump is not a representative of the median voter but instead a representative of the median electoral college elector. We can't have it both ways, rejecting the popular vote and then failing to acknowledge that our politics represent the electors and not the man on the street)
