Voter turnout among African American and Hispanic voters in the United States is surging, and this swell of minority participation could spell trouble for Donald Trump’s White House hopes.

On Sunday — the last day of early voting before Election Day on November 8 — hundreds of people attended “Souls to the Polls” events, aimed at encouraging churchgoers to vote across the key swing state of Florida.

Some came straight from morning worship, wearing three-piece suits and dresses as they made their way past dozens of campaigners hoisting signs for local candidates and urging support for solar energy and education issues.

At one event in central Miami, people held hands and prayed outside an early voting site, while at another in southern Miami-Dade County, about 20 African American men rolled in together on motorcycles.

For some, the vote they cast was as much for Democrat Hillary Clinton as it was against her Republican billionaire challenger.

“I’m scared if Trump wins,” said Ines Curbelo, 57, a nurse who described herself as Afro-Cuban and was handing out Democratic flyers at a polling place Cutler Bay, south of Miami.
