Tucker Carlson told viewers Monday on "Special Report with Bret Baier" that New Hampshire voters have changed dramatically over the last several years, making it more difficult than usual to predict the outcome of Tuesday's primary.

"This state has changed so much demographically, it's almost unrecognizable from 20 years ago. It's not exactly clear where those voters are going to go," the Fox News contributor said. "They're less religious, probably less strictly conservative in an orthodox sense. They're potentially Trump voters, in that they're non-evangelical, working-class voters. Will they go to him? I don't know."

Donald Trump has a decisive lead, with Florida Senator Marco Rubio trailing behind in second - nearly every poll headed into the primary potentially pulling in the "establishment" vote, though Carlson says voters may have reservations about the young senator.

"The establishment is swinging to Rubio, but they're nervous about him, and they think that the events of the debate night confirmed their pre-existing suspicions that he's fragile and not flexible," Carlson said.

Carlson added that the party, as a whole, needs to focus on winning over non-evangelical voters - a different demographic than was courted during the Iowa caucuses.

"They need to be thinking about how to win over those non-evangelical working-class voters who are the kind of pivotal chunk that the Republican party needs to win in November. And I don't see any evidence that they're thinking through how to do that."
