Those shirts are not new, and anyone who’s attended a Trump rally (or even a Bernie Sanders rally) this year will have seen them. Styled after Clinton’s 2008 logo, they produce frantic double-takes every time I see one, thinking a Hillary backer has gone out into the fray. But they’re especially popular here.

Then there are the speeches. One of the emotional peaks of Monday’s convention slate was a short address by Patricia Smith, whose son Sean Smith was killed in the September 11, 2012, terrorist attack in Benghazi while stationed there by the U.S. Foreign Service. As she told her story, someone on the floor shouting “Hillary for prison!”

“That's right,” Smith replied. “Hillary for prison. She deserves to be in stripes.”

Tuesday night, New Jersey Governor Chris Christie made it even more explicit. A former U.S. attorney, Christie approached his speaking slot like a prosecutor making his case against a defendant. He even asked the audience to deliver a verdict. “We must present those facts to you, a jury of her peers, both in this hall and in living rooms around our nation,” he said. “Since the Justice Department refuses to allow you to render a verdict, let’s present the case now, on the facts, against Hillary Clinton.”

The crowd was delighted to oblige. Throughout Christie’s speech, attendees broke into chants of “Lock her up! Lock her up!”

Still, these sentiments are by some measures the moderate ones. Al Baldasaro, a New Hampshire delegate who has appeared at events with Trump, railed against Clinton during a radio interview on Tuesday, as BuzzFeed’s Andrew Kaczynzski reported.

“Hillary Clinton to me is the Jane Fonda of the Vietnam. She is a disgrace for the lies that she told those mothers about their children that got killed over there in Benghazi. She dropped the ball on over 400 emails requesting back up security. Something’s wrong there,” he said. “This whole thing disgusts me, Hillary Clinton should be put in the firing line and shot for treason.”

On Friday, West Virginia delegate Michael Folk reached a similar conclusion, though he prescribed a different method of execution. Tweeting at Clinton, he said, “You should be tried for treason, murder and crimes against the U.S. Constitution… then hung on the Mall in Washington, D.C.”

The attitude that Clinton must be jailed or even executed is by no means universal. Some delegates seem as disgusted by the saber-rattling as they are by their nominee and the fights over rules at the convention—more signs of a party veering into populism and barbarity. Clinton is also an unusual figure in that she is plagued by some real legal problems, so it’s not just partisan animosity. But the Justice Department’s decision not to bring charges against Clinton over the use of her private email server inspired a harsh backlash. For months, Republican leaders suggested that Clinton would be indicted, despite legal experts’ consensus view that a prosecution was unlikely. When FBI Director James Comey dashed those hopes by recommending against charges, people who had gotten their hopes up were furious. Since the Justice Department won’t bring charges, people like Smith, Baldasaro, and Folk are making their own citizens’ indictments.
