Watch: Who might win the N.H. primary?

Despite national polls that show Donald Trump with a consistent and commanding lead in the New Hampshire primary, Rep. Frank Guinta, who represents New Hampshire's first congressional district, says the presidential race unfolding in his backyard is still "wide open."

"I think there's lots of room for movement for a whole host of candidates and not in any particular order, Carly Fiorina, Chris Christie, John Kasich, Marco Rubio, Ted Cruz and Donald Trump. I mean, he's been dominating in the polls for a period of time, much longer than anybody ever expected or anticipated," Guinta said in an interview with the Washington Examiner. "So I see this as a real wide-open race."

But the prospects for Jeb Bush in the Granite State have dimmed in recent weeks with the rise of outsider candidates like Fiorina and Trump — prompting alarm bells for some of his supporters who once saw New Hampshire as a crucial state to win.

Guinta said the former Florida governor might be in need of a campaign "reset."
