The movement to persuade President Biden—long after the primaries—to drop out of the Presidential race is unprecedented. So is the candidacy of a convicted felon. But this election season went from startling to shocking with the assassination attempt on Donald Trump and the death of a bystander. Despite the unknowns, the contours of the race are becoming clear, the CNN data journalist Harry Enten tells Clare Malone. President Biden’s support in national polls following his disastrous performance in the June debate slipped just slightly. But in key swing states, Biden’s support has ebbed to a point that has terrified Democrats. Malone spoke with Enten while he was covering the Republican National Convention, in Milwaukee. She asked Enten about how the attempt on Ronald Reagan’s life affected his favorability. Malone also spoke with the highly regarded pollster Ann Selzer, who runs polling for the Des Moines Register. Selzer explains how the polls know what they know—even when so many people don’t pick up their phones.
