If Trump doesn’t win, some are even openly talking about violent rebellion and assassination, as fantastical and unhinged as that may seem.

“If she’s in office, I hope we can start a coup. She should be in prison or shot. That’s how I feel about it,” Dan Bowman, a 50-year-old contractor, said of Hillary Clinton, the Democratic nominee. “We’re going to have a revolution and take them out of office if that’s what it takes. There’s going to be a lot of bloodshed. But that’s what it’s going to take . . . I would do whatever I can for my country.”

He then placed a Trump mask on his face and posed for pictures. . . .

His supporters are heeding the call [to monitor the polls]. “Trump said to watch your precincts. I’m going to go, for sure,” said Steve Webb, a 61-year-old carpenter from Fairfield, Ohio.

“I’ll look for . . . well, it’s called racial profiling. Mexicans. Syrians. People who can’t speak American,” he said. “I’m going to go right up behind them. I’ll do everything legally. I want to see if they are accountable. I’m not going to do anything illegal. I’m going to make them a little bit nervous.”
