He couldn't do that since it would prove he was just another petty dictator, could he? Not while the liberals and leftists were working so hard to prove he was an exceptional president not prone to corruption, unlike the vitriol they poured upon Trump 24/7! Now that it is all rendered into nothingness, Biden showed his true nature because he has nothing to lose. The Democrats betrayed him for Kamala. So he doesn't care about his nonexistent legacy, knowing very well no one bought it, and least of all, the ordinary American majority. A fitting end for a corrupt shell hollow politician, atleast in terms of American legacy,
So don't pretend for the nonexistent virtues of a man you yourself stabbed in the back; he himself doesn't care to protect the Democrat legacy anymore, having been betrayed and abandoned in the heat of battle. Just realize the game is over. Khallas! Khatam!
