His numbers don't suck. The race is still a toss up and he's even favored. That's petty good given the debate, the media frenzy for two weeks, the Dem firing squad, Trump nearly getting whacked and the RNC.
Biden never said he would be a one term president. There seems to be a Mandela effect going on.
He was never a great speaker. He always made gaffes. He once called Obama Barrack America. If he was as great as a speaker you say, he's previous campaigns wouldn't have collapsed before Iowa.
He's literally been campaigning every day. He's done rallies, interviews, and a press conference. Trump did one rally outside of his golf course since the debate.
