Joe Biden leads the Presidential race in Pennsylvania by around ten per cent, according to most polls, but Eliza Griswold says you wouldn’t know it on the ground. Republicans in the state have organized a huge registration drive in recent years, and, while Griswold was driving to Biden’s working-class birthplace of Scranton, she saw Trump signs blanketing the lawns and roads. Peter Slevin, reporting from Wisconsin, tells David Remnick that Democrats there organized early, to avoid the mistake that Hillary Clinton made in 2016 of taking the state for granted. Even so, Biden’s campaign has declined to do risky in-person events, but the Trump campaign, until recently, has proceeded as if coronavirus had never happened.
