If it were me, I would be finagling behind the scenes to have Vance agree to the following plan: Once I, the President, resign, for health reasons, he automatically rises to President, at which point he pardons me, my family, my entire massive gang of grifters and insurrectionist, and then Vance agrees not to run again for President and the Republican Party has a full primary season and somehow find a non-Trump rational person to run for office.
It is what Nixon did though they first had to fire their sitting VP, Agnew, and have the party hack, Gerald Ford, become VP and then President.
The war we should be fighting...against human caused global warming.
The war we are fighting...against our own Constitution, led by the clear fascist Trump.
In order to win, our Executive Branch needs to lose.
