He's going to care if he wins in the criminal trials, especially the one in Georgia he couldn't definitely pardon if he was president. He probably couldn't pardon the others because it's legally questionable whether a president can pardon himself, but he'll sure try.

Idk, assuming you have bills to pay you'll want to be able to get paying work in the future (especially since TFG won't be paying), which is harder if googling your name comes back with nothing but clown pictures.
