Trump's base, as everyone knows but for some reason is unwilling to point out, is mainly white men and married white women. Clearly everyone is an individual and there's probably a single black woman somewhere who voted for Trump, but without those white voters he has absolutely no chance.
Why does that matter? Because they're completely disillusioned with him. The spectacle was well and good, but rather than focusing on the concerns of his base, like border security, immigration, creating blue collar jobs, and trade school scholarships just to name a few, his greatest achievements are Operation Warp Speed, which they don't like, and the usual tax cuts for the rich, which they don't care about. His main tangible policy that benefitted the white working class was not sending their sons off to die in a new pointless foreign war.
The upshot of all that is that you can rest assured that Trump hasn't got a prayer of winning reelection in 2024 and I'm near certain that his team knows it.
