Voters cast ballots in eight states and the District of Columbia Tuesday in primary and municipal elections marred by the coronavirus pandemic and police and military crackdowns on street protests, with voting rights activists warning of widespread disenfranchisement. In Washington, D.C., and Philadelphia, where polling places remained open even as curfews went into effect, officials said people had permission to be out of their homes if they informed police of their intention to vote. In Baltimore, election officials opened just six in-person voting sites, citing the pandemic. At one polling place, about 100 people — most of them African American — were still waiting to cast their ballots around 10 p.m. Tuesday night.
