CLAREMONT, N.H. — Republican front-runner Donald Trump said he believes President Obama’s executive order on guns will give his own supporters another reason to go to the polls.

“He shouldn’t be doing it by executive order,” Trump told the Herald backstage, moments before rallying supporters here last night. “I mean, you should be getting Congress together and there’s supposed to be agreement. All they’re doing is step-by-step, they’re hurting the Second Amendment, and that’s all they’re doing.”

Trump added: “You have to go out and you have to cajole and deal with Congress … and not just sign something you feel like signing. He has to be able to make deals and get the Republicans and Democrats together and make deals.”

Trump said Obama’s new gun rules could ultimately backfire, helping to get Trump’s supporters to the polls.

“I think it might,” said Trump. “We have such tremendous support, but I think something like that probably might …”

“Look at Paris,” he added. “If you had people in that room that had a revolver strapped to their belt, they had a gun strapped to someplace and … the good guys could do a little shooting back, it wouldn’t have been 130 people killed — that I can tell you.”

In the past few days, Democratic front-runner Hillary Clinton has accused Trump of sexism and Trump has said former President Bill Clinton’s sex scandals are “fair game” on the campaign trail.

Trump and Bill Clinton were stumping just a few miles apart Monday night, but didn’t take shots at each other.

But Trump said last night, “When he puts himself out there, he becomes fair game. I think everybody saw that. Once he puts himself out there, he’s absolutely fair game.”

The big question for Trump — still leading polls nationally and in New Hampshire, including the latest Franklin Pierce University Boston Herald poll last month — is whether he can get his supporters to the polls.

Many haven’t voted in years, and Trump has been criticized for not having as strong a ground game as other candidates, such as Jeb Bush.

But Trump said, “I think we have a great ground game. Some of them are right here now. … And I think we’re going to do really well. New Hampshire’s been very strong. We’re leading in every poll by a lot, some numbers are by tremendous amounts.

“If everybody shows up, we’re going to have a great situation. We’re going to make America great again. It’s going to be very simple. There’s a lot of love in the air, I can tell you. There’s tremendous spirit for the country.”

Hundreds of Trump-backers waited in the cold — some for more than an hour — to get into the high school gymnasium here.

“Washington’s corrupt,” said Scott Lavertue, a disabled Navy veteran and Trump supporter from Quechee, Vt. “I can’t get even started, man. I’d love to see … Trump and Bill O’Reilly as his running mate. How’s that?”
