From the Daily Beast:
During an Iowa town-hall forum, Biden was confronted by a voter who identified two problems he has with the ex-veep: He’s too old and his son Hunter was “messing around” in Ukraine.
“You’re a damn liar, man, that’s not true,” Biden fired back before challenging the man to feats of strength: “And you want to check my shape, let’s do pushups together here man! Let’s run, let’s do whatever you want to do. Let’s take an IQ test.”
Biden went on to say:
“Well, I knew you weren’t voting for me, man,” Biden said. “You think I thought you’d stand up and vote for me? You’re too old to vote for me.”
Biden then mentioned that he had an onion on his belt, which was the style at the time.
Journalists talk about how in the Democratic race there are ideological “lanes” such as Progressive and Moderate, but it actually looks more like there are class/personality lanes, with Warren and Buttigieg in the Stuff White People Like lane and Biden and Bernie in the Regular Folks’ Grandpas lane.
