Ahead of the November midterm elections, top Democrats are planning for doomsday scenarios for how Donald Trump and his administration could intervene in the voting process and laying the groundwork for a forceful response.

In closed-door meetings, Senate Minority Leader Chuck Schumer has convened Democratic senators, legal experts, and former officials to discuss highly specific hypothetical situations, including Trump deploying Department of Homeland Security agents and the National Guard to the polls, federal officials seizing ballots after the administration announces a foreign adversary compromised voting systems, and fake, AI-generated videos alleging election fraud sparking demands for intervention from Trump that lead to a purge of eligible voters from the rolls.

“These sessions didn’t just help us work out how we can thwart some of Trump’s egregious threats. They have been critical in helping us imagine the many twists and turns Trump and his cronies could throw at us, and where gaps in our preparation could potentially exist. I feel more confident — and the American people should, too — that we’re better prepared heading into the election because of our efforts,” Schumer said in a statement to CNN.
