Joe Biden was brilliantly and gloriously adequate
To Castro: "I have guts enough to say his plan doesn't make sense."
His rejoinders were of varying quality, but Biden accomplished important things: While others attacked him, he repeatedly returned the focus to Trump, he stuck to his moderate positions, and he tied himself closely to Obama. "Everybody is talking about how terrible I am on these issues," he said. "Barack Obama knew exactly who I was. … He chose me, and he said it was the best decision he made."
After one of several attacks by an incessantly nasty de Blasio -- the former vice president smiled and said: "I love your affection for me. You spend a lot of time with me."
De Blasio, who declared "victory" because Biden had changed the position he held on the North American Free Trade Agreement 25 years ago, replied: "We believe in redemption in this party."
"Well," Biden said dryly, "I hope you're part of it."
Not a bad line -- on not a bad night for Biden. In fact, it was brilliantly and gloriously acceptable.
