Moderator Linsey Davis asked Biden, 76: "In a conversation about how to deal with segregation in schools back in 1975, you told a reporter, 'I don't feel responsible for the sins of my father and grandfather. I feel responsible for what the situation is today, for the sins of my own generation, and I'll be d----- if I feel responsible to pay for what happened 300 years ago.' "
"You said that some 40 years ago," Davis continued. "But as you stand here tonight, what responsibility do you think that Americans need to take to repair the legacy of slavery in our country?"
Biden responded: "Well, they have to deal with the - look, there's institutional segregation in this country. From the time I got involved, I started dealing with that. Redlining banks, making sure we are in a position where - look, you talk about education. I propose that what we take is those very poor schools, the Title I schools, triple the amount of money we spend from $15 to $45 billion a year. Give every single teacher a raise, the equal raise to getting out - the $60,000 level."
"Number two, make sure that we bring in to help the teachers deal with the problems that come from home. The problems that come from home, we have one school psychologist for every 1500 kids in America today. It's crazy. The teachers are - I'm married to a teacher, my deceased wife is a teacher. They have every problem coming to them. Make sure that every single child does, in fact, have 3-, 4- and 5-year-olds go to school. School. Not daycare. School. We bring social workers in to homes and parents to help them deal with how to raise their children.
"It's not that they don't want to help. They don't - they don't know quite what to do. Play the radio, make sure the television - excuse me, make sure you have the record player on at night, the - the - make sure that kids hear words. A kid coming from a very poor school - a very poor background will hear 4 million words fewer spoken by the time they get there."
So the moderator asked about America's original sin - slavery - and Biden somehow got to turning on record players, which wasn't an effort to coax the hipster vote away from Bernie Sanders, no matter how much the millennials love vinyl.
It was an incoherent, rambling illumination of the key knock on Biden: He's too old. Former housing and urban development secretary Julián Castro, during the debate, and Cory Booker, afterward, made this argument, first indirectly, then directly, but they didn't need to. Biden indicted himself on the age question.
If President Donald Trump abandons "Sleepy Joe" for "Record Player Joe Biden" on Twitter, the tattoo on Biden that is probably already permanent gets inked in bright colours. Manhattan-Beltway media may scoff at the single-phrase branding, but every marketer knows it works and works and works.
"Record player" is like Chris Christie's campaign-killing knockdown of Marco Rubio at a New Hampshire debate. "There it is. There it is," declared Christie onstage. "The memorised 25-second speech. There it is, everybody." Rubio and his supporters gamely tried for days to argue that what Christie said didn't matter. It did. It was over for the Florida Republican. A campaign-slashing branding of "robotic" stuck. Just as "record player" will.
