In the past month, a fracture has opened up in the G.O.P. between those who grudgingly accept Joe Biden’s win and those who falsely claim that the election was rigged. In Georgia, supporters of Donald Trump have turned on Republican election officials—in some cases, with threats of violence. The Atlanta-based staff writer Charles Bethea explains why this rift is dangerous for Republicans. Georgia’s two incumbent Senate seats are up for grabs in a runoff election in January; the G.O.P. needs to retain at least one to maintain its majority and to give Mitch McConnell near-veto power over the Biden agenda. But the more that the President and his followers attack the election, the less likely Republican voters are to turn out to vote—which would create an advantage for the Democratic Senate hopefuls. Bethea spoke with Gabe Sterling, an election official in Georgia; Lin Wood, an attorney who is fuelling conspiracy theories; and voters at a Trump rally in Valdosta. Plus, protests against police violence took place around the world this year; in Nigeria, they might lead to the undoing of a notoriously lawless and brutal police unit.
