When people here watch Trump rallies, some see imagery that reminds them of their childhoods in the Deep South; some go so far as to wonder if Mr. Trump’s supporters have been planted by the Ku Klux Klan. Their feelings about Mrs. Clinton are mixed, but those who are voting for president will vote for her.

They hold Republicans in disdain. But their reaction to Mr. Trump is especially deep and visceral.

“Back to slavery days,” Ms. Solomon said gravely. “Do as master say.”

But if Mr. Trump has brought racial animus to the fore, some see that as a blessing. “It kind of pulled a blindfold off of America,” Inez Muhammad, 54, a disabled federal worker, said.

Like many here and across the nation, Ms. Solomon is looking past Election Day: She fears that Washington “will be a mess,” with Mr. Trump kicking up a fuss if he loses. She has been working on her résumé and intends to re-enroll in college, to prove to her grandchildren that “if Nana can get a degree, you can too.”

In the meantime, she has volunteered to help Democrats register voters and pushing everyone she knows to go to the polls, especially her grandson, who is 18. “I told him, that’s not a given right for black people,” she said. “Too many people died for you to give up that right.”
