Threatening his Republican and Democratic opponents with violence played a major role in Donald Trump’s campaign for President.

No other candidate—Republican or Democrat—had ever made such repeated and brutal use of threats of physical assault in pursuing the Presidency.

• Philip Klein, the managing editor of the Washington Examiner,  wrote on the eve of the Republican National Convention in July: “Political commentators now routinely talk about the riots that would break out in Cleveland if Trump were denied the nomination, about how his supporters have guns and all hell could break loose, that they would burn everything to the ground. It works to Trump’s advantage to not try too hard to dispel these notions.”
• On August 9,  Trump told a rally in Wilmington, North Carolina: “Hillary [Clinton] wants to abolish, essentially abolish, the Second Amendment. If she gets to pick her [Supreme Court] judges, nothing you can do folks. Although the Second Amendment people, maybe there is, I don’t know.”
• “Don’t treat this as a political misstep,” Senator Christopher S. Murphy of Connecticut, who has called for stiffer gun laws, wrote on Twitter. “It’s an assassination threat, seriously upping the possibility of a national tragedy & crisis.”
• “Well, let me say if someone else said that outside of the hall, he’d be in the back of a police wagon now, with the Secret Service questioning him,” said Michael Hayden, former head of the CIA and National Security Agency (NSA). 

Making threats against anyone under protection by the U.S. Secret Service is a felony. Yet Donald Trump was never held legally accountable by the Justice Department.

Threats of this type continued to be made by Trump supporters right up to the day of the election.

• On July 29, Roger Stone, a notorious Right-wing political consultant acting as a Trump strategist, told Breitbart News: “The first thing Trump needs to do is begin talking about [voter fraud] constantly. If there’s voter fraud, this election will be illegitimate, the election of the winner will be illegitimate, we will have a constitutional crisis, widespread civil disobedience, and the government will no longer be the government.”
• At a town hall meeting where Trump’s Vice Presidential nominee Mike Pence appeared, a woman named Rhonda said: “For me personally, if Hillary Clinton gets in, I myself am ready for a revolution.”
• In Cincinnati, a Trump supporter threatened to forcibly remove Clinton from the White House if she won the race: “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.”

Even Fergus Cullen, former chairman of the New Hampshire GOP, expressed fear of what might happen if Trump lost the election:

“That’s really scary,” Cullen said, recounting the violence at Trump rallies around the country leading up to the Republican National Convention. “In this country, we’ve always had recriminations after one side loses. But we haven’t had riots. We haven’t had mobs that act out with violence against supporters of the other side.

“There’s no telling what his supporters would be willing to do at the slightest encouragement from their candidate,” he said.

Trump even began encouraging his mostly white supporters to sign up online to be “election observers” to stop “Crooked Hillary from rigging this election.” He urged them to act as poll watchers in “other” [non-white] communities to ensure that things are “on the up and up.”

Many of his supporters promised to do so.

“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.”

Knowing that large numbers of angry—and possibly armed—Right-wingers planned to descend on polling places could only have had a chilling effect on untold numbers of Democratic voters. And this would have been especially true in heavily conservative states.

Both the USA Patriot Act and the Racketeer Influenced Corrupt Organizations (RICO) Act have statutes dealing with making terrorist threats against government institutions to influence their members.

If Trump’s remarks did not violate one or both of those laws, certainly remarks made by his surrogates did.

Thus, the Justice Department could have cited the Patriot Act in indicting Trump and/or any number of his followers for “activities that…appear to be intended…to influence the policy of a government by intimidation or coercion [and]…occur primarily within the territorial jurisdiction of the United States.”

The Justice Department could have also demanded that the results of the election be invalidated on the basis that widespread voter and candidate intimidation played a massive role in it.

But of course this did not happen.
