At the mildest, surely it would be informative to learn if the former senator from Delaware agrees with Wilmington’s recent decision to remove a statue of the state’s most famous son, Caesar Rodney, from downtown. Rodney is known in American history for riding 80 miles through a storm to get to Philadelphia in time to cast Delaware’s deciding vote for independence. His statue was removed because, like several other Founding Fathers, he owned slaves.

Notwithstanding calls for Mr. Biden to declare himself on the issue, he’s clearly betting that a press corps that managed to ignore a former Senate staffer’s charge of sexual assault for weeks won’t press him on the statues and the mayhem. No doubt he is betting correctly.

On paper, this should be an easy call. The Democratic voters, especially African-American voters, who made Mr. Biden their nominee did so on the belief they were going with the moderate. But Mr. Biden has been under relentless pressure to move left, and he’s obliged by flip-flopping on many positions that made him a moderate—from his support of the 1994 crime bill to his initial rejection of the Green New Deal.
