PHILADELPHIA, PA (WITF) – It’s not easy to recognize important historical moments while they’re happening. But 2020 has been a year marked by disaster and debacle. It has featured a deadly global pandemic, a reckoning over racism in the wake of several Black Americans killed by police, and a tense, litigious election. Looking back, historians, political insiders, and on-the-ground organizers agree that the last 12 months or so will leave an indelible impression. “I don’t know a historian right now who isn’t still kind of in shock,” said Timothy Lombardo, a Philadelphia-born historian of conservative politics.
