I've never seen anyone who makes this argument establish exactly which segments of the population have grown to hate Trump since 2016 who didn't before then. The idea that, for example, he's done something to alienate female Boomers who weren't already turned off by "Grab em right in the pussy" is ludicrous. The only people I've seen turn against Trump in the years since 2016 are the Conservative Inc and neocon "influencers" who only supported him to begin with because they're a bunch of ambulance-chasing grifters, and hitched their ride to DeSantis because Trump didn't provide them with the attention or compensation they felt they deserved.
