PORTSMOUTH, N.H. – Democratic presidential candidate Andrew Yang says he’s not going to get too crazy on New Year’s Eve.

“Probably not. I’m campaigning tomorrow, too, so it would be unseemly for the candidate to get sloshed or anything on New Year’s Eve,” the tech entrepreneur told Fox News on Tuesday afternoon as he kicked off the first of a half-dozen events to ring in 2020 in New Hampshire, the state that holds the first primary in the race for the White House.

“I need to be at it again tomorrow. So you know, you have to maintain control of your faculties,” noted Yang, who's been known to cut it up on the campaign trail.

Yang -- the onetime-long shot-turned-middle-tier Democratic nomination contender -- will culminate his day with a sold-out New Year’s Eve party at a brewpub in the city of Nashua. Even though he says he won’t be getting crazy, he said: “I hope that people around me, though, do feel free to indulge, do whatever they want, because hey, it’s New Year’s Eve and it’s party time.”

And his message to his supporters is “don’t let me be a stick in the mud because I’m going to be in an excellent mood and we’re going to ring in the New Year right, and then we’re going to help make the '20s the decade that we’re proud of to reverse a lot of the stuff that’s gone on in this country over the last number of years, unfortunately.”

Sen. Amy Klobuchar is ringing in 2020 with her New Hampshire campaign staff and volunteers. The event wraps up a jam-packed three-day swing through the state by the Minnesota Democrat.

And Rep. Tulsi Gabbard of Hawaii -- who is renting a home in the state through the Feb. 11 primary -- held a town hall in Portsmouth in the late afternoon.
