You are on to something here. Think of it this way: Trump wanted to beat Biden. He wanted to prove he wasn't a loser. Biden dropping out means he will never get the chance. Like a boxer who got knocked out, trains for 4 years for a rematch, and his opponent retired with the belt.I don't think what he says and does even matters anymore. He's an avatar for the remaining MAGA movement that hasn't decided being pissed off all day every day at (mostly) straw men doomsday actors is exhausting while nothing ever happens.
Personally, I think he's just hoping bitching and complaining about whatever he calls "Radical Left" and "Election Interference" and the Border (legitimate as it may be) will be enough to either cause him to fail upwards again, or cause another "guided tour" at the Capitol in his honor.
I don't think he even wants to be president again except it's the only way to soothe his ego from his loss to Biden before he pops a blood vessel and falls over from a stroke. It's why Biden dropping out has sent him into an absolute tailspin he can't seem to pull out of. The dude wrote fan fiction, a few times, about Biden secretly still running, who will show up ANY MOMENT NOW to challenge him and sent that shit for the world to see.
Now he's been shot at and KopMalla is pulling crowds bigger than his. His ego can't handle it. Going so far as to just throw it out there that it's all AI and hoping it stuck was desperate af.
He's lost his muse.
The seethe could power a city.
