“Politics ain’t beanbag,” the fictional Mr. Dooley once observed. So it should have come as little surprise to former vice-president and Scranton native Joe Biden that elements of his long political career could and would be used against him, fairly or not. Case in point: California Sen. Kamala Harris’ attack during the recent round of Democratic presidential debates, wherein she painted Biden into a corner over his record regarding federally mandated busing as a way to alleviate segregation four decades ago. Whether or not it’s accurate — or, like I said, “fair” — to view a complicated issue from a different era through a modern lens is one matter. What’s clear is that Harris managed to score a hit, dinging Biden’s commanding lead in the polls.
