“The dude looks like Hollywood,” Mr. Wilson said, looking at Omar J. Dorsey, who plays a lead in “Queen Sugar,” a show created by Ava DuVernay that follows families running a sugarcane farm in the South. He and Mr. Dorsey exchanged bear hugs and selfies, and Mr. Wilson told him not to worry — he had already cast his vote early for Stacey Abrams, after waiting in line more than an hour and half.

“I feel good about it, but we got to knock it out of the park,” Mr. Wilson said.

The “Queen Sugar” actors were deployed by Care in Action, which has fielded hundreds of canvassers, many of them child care workers, home health aides or housecleaners, to reach voters of color. They gathered Saturday morning at a roller-skating rink and spent all day knocking on doors as well as dropping in on barbershops and beauty salons.

Next stop, a few doors down, was the House of HHC Beauty Lounge. Latitia Lamkin-Brooks, getting her hair done, was giddy at the sight of Mr. Dorsey’s co-star, Dawn-Lyen Gardner.

Ms. Lamkin-Brooks tried to coax details about next season’s plot, but gave her word: she’d show up on Tuesday.

President Trump returns to Montana

BELGRADE, Mont. — Greetings from Montana, where the Bridger Mountains serve as what might be the most picturesque backdrop of a “Make America Great Again” rally to date. The president spent an hour here on Saturday afternoon delivering his closing midterm argument to residents of Big Sky Country.

While President Trump stuck to his usual themes — castigating immigration policies, Democrats and Democratic immigration policies — he was less fired up than he was at his appearance in Missoula just over two weeks ago, when he praised the Republican Congressman Greg Gianforte for body-slamming a reporter.

Still, this time, his visit here was personal: The president reserved several minutes of special attention in his efforts to put a pin in the campaign of Jon Tester, the Democratic incumbent struggling to fend off a challenge from Matt Rosendale, whom Mr. Trump was here to support.
