Eh I would say Carter got it bad because he was a man of faith during the WOAT of times. The dude basically wanted folks to "pray on it", and as a Christian marsupial, it's understandable, but on an American side of things, you're going to have to make them dope moves to keep the lights on.
Biden was basically dragged in during the most damaging times of America. The pandemic, racial injustice, wars going on between Russia/Ukraine, and had to pick a side with Palestine and Israel. Bad enough, dude showed signs of terrible aging and health woes. Carter on the other hands was fresh in his 50s.
Also, it doesn't help that he didn't have a security blanket to help with a potential 2nd term. You had this demonic Hollywood actor that gloating about wealth and jobs, only for them bytches to get bushed with the quickness. Dumb ass Americans jump on the Greico Wall street coke head wave, folks were tired of dealing with hanging in a chow line type of steez.
