His performance was unnerving. I don’t want Biden to be the nominee for ideological reasons, but polls show him far ahead, and if he’s going to be the Democratic Party’s standard-bearer against Donald Trump, I want him to be a strong one. He didn’t seem strong in South Carolina.

Donald Trump, of course, also speaks in gibberish, but with a bombastic unearned confidence; rather than flailing around for the right figure he makes one up. Biden, by contrast, was just shaky. And while there’s great affection for him on the ground, there’s little excitement. You can see why his campaign has been limiting his public events and why he’s been avoiding the press.

It’s true that ordinary voters don’t seem to care about the gaffes that obsess cable TV commentators. No one I spoke to in Columbia was bothered by Biden waxing nostalgic about his civil relations with segregationist senators; most people hadn’t even heard about it. And his ability to forge personal connections remains impressive. At the fish fry, his remarks were surprisingly short, but he stayed until almost midnight talking to attendees one-on-one on the rope line.
