“How can he possibly win from a jail cell?”
Because nothing prohibits him from running from a jail cell, and he would still meet all Constitutional requirements for POTUS. He could win if he gets enough votes. Sadly, they will be more BALLOTS (manufactured) against him than there will be actual legal VOTES for him. RATS have the system fine tuned.
PDJT from prison still would be better than any of the others foot-loose and fancyfree.
He can run from a jail cell. You really think that if he does he could possibly win?
