WATCH: Donald Trump Flinches as Man Rushes Stage at Ohio Rally

DAYTON, OH - A man hopped a barricade Saturday and attempted to rush the stage where Donald Trump was addressing a rally in Dayton, Ohio. Secret Service agents tackled him about two seconds into the attempt while four other agents formed a human wall around the frontrunner for the GOP presidential nomination.

Trump, visibly startled, grabbed the podium for a scary few seconds as some people in the crowd screamed.

“Thank you for the warning," he told the crowd as the man was led away. "I was ready for him, but it’s much easier if the cops do it.”

The man was taken into custody without incident by Secret Service Special Agents and Dayton Police Officers, a Secret Service spokesman said in an email to Patch. The spokesman added that Trump was able to finish delivering his remarks.

In any other campaign, the immediate assumption might be that the man was mentally ill or drunk enough to make an ill-advised attempt to get between Trump and the many cameras trained on him.

This, of course, is not any other campaign. Trump events are now regularly marked by scuffles, sucker punches, screaming and other outbursts that not long ago would have been considered unthinkable at campaign events for presidential candidates.

The incident occurred only hours after Trump decided to cancel a rally in Chicago out of safety concerns. Supporters and protesters there had been squeezed into the area where he was to speak, taunting each other with name calling and profanity, when they were told of the cancelation.

That's when the "rally" began to look more like a scrum, with fists, bottles and threats flying.

Every candidate remaining in the race, Democrats and Republicans alike, blamed Trump for the violence, citing the tone of his campaign, which has centered on name calling, immigrant bashing, discrimination based on religion and demonstrable lies, all to tap into the discontent of less than half of the Republican party.

Ohio's governor, John Kasich, in a tight race with Trump in the state's primaries Tuesday, went after him.

"Donald Trump has created a toxic environment," Kasich told reporters. "And a toxic environment has allowed his supporters and those who sometimes seek confrontation to come together in violence. There is no place for this, there is no place for a national leader to prey on the fears of people who live in our great country."

Rather than defuse the tensions and ask his supporters to let security handle disruptive, but peaceful, protesters, Trump went to his old fallback in his first rally after Chicago, defiantly blaming someone else for his failing, this time supporters of Democratic candidate Bernie Sanders and Sanders himself.

“As is the case virtually every day, Donald Trump is showing the American people that he is a pathological liar," Sanders said in a statement. "Obviously, while I appreciate that we had supporters at Trump’s rally in Chicago, our campaign did not organize the protests.

“What caused the protests at Trump’s rally is a candidate that has promoted hatred and division against Latinos, Muslims, women, and people with disabilities.”

In fact, Trump has stoked anger among those at his rallies.

At a recent event, he told supporters he had heard he would be pelted with tomatoes.

"So if you see somebody getting ready to throw a tomato, knock the crap out of 'em, would you? Seriously," he said. "Okay? Just knock the hell — I promise you, I will pay for the legal fees. I promise. I promise."

Last week, one of his supporters followed his leader's orders, sucker-punching a protester as he was willingly being led from the building.

Never mind that the man had no tomatoes.

In Saturday's incident in Dayton, Trump had just finished ridiculing a protester, telling security to "take him home to mommy," when the man who tried to get at himp made his move.

The man, identified as, Thomas Dimassimo, was charged with disorderly conduct and inducing panic, Chief Mike Etter of the Dayton Airport Police Department told NBC News.

Later, at a rally in Cleveland, he was interrupted several times again. When he could speak, he called Kasich "a baby."

By the time Trump got to Kansas City for his last campaign event of the day, protesters planted in the audience took turns interrupting him and being escorted from the rally.

This time, police did the escorting. "Don't hurt them," he told his supporters. "But these people are terrible for the country."
