Not just the Virginia Democrats: Biden once sang praises of segregationist George Wallace
People often forget that durring segration the Democats controlled the South. Jim Crow, the height of the KKK, "segregation now, segregation forever!", all happened when the Democratic Party was in power.
That isn't to say that as the South slowly became Republican that all racist tendencies disappeared in the South. (Racism, in our experience can be worse in the North by the way.) Indeed, a big part of the drift in the South to the GOP came after and because pro-big government Democrats moved on the Civil Rights Act. But the harshest, most horrific racism, the most institutionalized racism in the South occured under rule by FDR's party. (FDR interned American citizens of Japanese dissent during World War 2 for the sole reason that they had ancestors who were from Japan it must be remembered. That happened in California.)
And though Delaware has changed over the last decades and now generally looks to the Northeast, it was once, when Biden came on the scene, a pretty southern state. It is a state with a history of agricultural slavery. (As opposed to slavery in the North which was more servant oriented.)
Though Biden may want to run from his praise for a segregationist, not to mention reports of his alleged tendency to swim naked in front of female Secret Service agents, he's going to have a tough time in this information age. In some ways Biden is Trump's dream Dem candidate.

"I think the Democratic Party could stand a liberal George Wallace — someone who's not afraid to stand up and offend people, someone who wouldn't pander but would say what the American people know in their gut is right,” Biden told the Philadelphia Enquirer on Oct. 12, 1975, referring to the racist then-Alabama governor...
...Biden's 1975 comments came on the heels of a legislative victory in the Senate, when he sponsored an amendment to prevent the federal government enforcing busing policies to desegregate school districts. Biden’s amendment appalled civil rights activists who claimed it set back desegregation efforts and struck down parts of the Civil Rights Act.
