Biden has several options.
He could quit and hope he doesn't get indicted.
He could keep going and try to pull off one more big score before Trump whups his ass in November.
He could be so afraid of bankruptcy and what is coming, that he ignores all the calls to step aside and puts it all on the line for four more years of "you cannot indict a sitting resident."
I'm leaning toward the last option.
I have always thought his 2020 run was motivated by greed and for the legal protection against indicting a sitting president. Even then, he knew some were poking around in his 'family business.'
Even dementia patients can be lucid part of the time (debate was bad timing - the sundowner effect), so I feel like Joe is going to ignore the reality of the polls, ignore the pleas from Demo-rat insiders, and try to make one more big score and put it all on the line for the four more years of the indictment free con game.
