Trump has no interest in actually governing. He never had any interest in governing. He just wants an audience so he can play a "winner" on TV. He thought, like any starring role, playing a World Leader would be a great way to get rich.
I suspect his "fans" (the ones who go to rallies) want to be entertained. Politics is boring. They don't understand it or have the patience for it.
Trump tells them they're the elite, and would be at the top of the hierarchy if the 'others' weren't taking what belongs to them.
The explanation is that Trump is incapable of doing anything other than what he is doing. He can't plan. He can't govern. He can't alter his behavior. He can't care whether people die of COVID.
