I think Joe is wandering around, trying to challenge everyone who didn’t vote for him to a push up contest.
He’s on tape telling more than one person who challenged him on something to “vote for someone else”. I guess they listened.
One guy said “I’d back you in a general but...” Biden: “I’m not looking for general election voters”
And in 1988 after he got caught lying about his academic record he told an irate voter he would beat him in an IQ contest.
