It’s Election Day in Arizona and elderly voters in Maricopa County are told by phone that local polling places are closed due to threats from militia groups.
Meanwhile, in Miami, a flurry of photos and videos on social media show poll workers dumping ballots.

This simulated scenario was part of a recent exercise in New York that gathered dozens of former senior U.S. and state officials, civil society leaders and executives from technology companies to rehearse for the 2024 election.
