BEDFORD, N.H. — Donald Trump stumped Thursday in the state where he clinched his first primary victory, promising a limitless future if voters seized what he framed as a once-in-a-lifetime chance to deliver him all the way to the White House.

“You have 40 days to make every dream you’ve ever dreamed for your country come true,” the GOP presidential nominee said at the NH Sportsplex. “Do not let this opportunity slip. I don’t believe you’re ever going to have this opportunity again.”

The candidate, meanwhile, portrayed the current state of the country as bleak and fixed under what he and supporters have denounced as the establishment.

“The Clintons are the sordid past,” Trump told about 2,000 supporters who stood on the artificial turf of the sports arena. “We will be the very bright and clean future.”

He sought to draw attention to the immunity granted to a handful of people in the federal investigation into Hillary Clinton’s use of a private email server during her time as secretary of state. As part of a campaign against his Democratic opponent themed “follow the money,” Trump denounced the “FBI Immunity Five.”

He suggested that Clinton herself may also have immunity.

Additionally, Trump has grown more and more criticial of “NBC Nightly News” host Lester Holt’s performance as moderator of last Monday’s debate at Hofstra University.

“I had to put up with the anchor and fight the anchor all the time on everything I said,” he said. “What a rigged deal.”

Trump vowed to curb heroin abuse in New Hampshire, saying the “poison” is killing young people here and adding that his campaign promise to build a wall along the southern border of the United States would stem the flow of illegal drugs into the country.

Clinton holds a very narrow lead in recent polls of Granite State voters, who in 2012 chose President Barack Obama over Mitt Romney.

On Wednesday, Clinton and now-ally Sen. Bernie Sanders (I-Vt.) hosted an event on the need for debt-free high education about 40 miles away in Durham, New Hampshire.

Both the Clinton and Trump campaigns have struggled to harness the millennial enthusiasm that boosted Sanders in the Democratic primary and won the presidency for Obama.

State Senator Andy Sanborn (R-Bedford), in opening remarks before Trump’s speech, criticized Clinton and Sanders’ message on the cost of education, saying nothing is free.

“Hillary must have missed that Economics 101 class,” he said. “So, for all you sub-21s who are working your way through college, it ain’t free because somebody’s paying for it.”

Several people in Bedford echoed a sentiment expressed by Trump backers nationwide: that the Republican is the people’s candidate.

“He speaks like me. He stumbles over his words,” said Matt McGilvery, 49, of Revere, Massachusetts, who wore a visor covered with stickers saying Trump supporters are “real Americans.” “He’s not a normal politician.”

Dave Moore, 50, of Greenland, New Hampshire, brought his 15-year-old son and son’s friend. All wore hooded sweatshirts with American flag print.

“I’m tired of the establishment,” said the elder Moore, who works in sales. “I’m tired of people telling you what you want to hear and then doing the opposite when they get to Washington, D.C.”
