MANCHESTER, N.H. (WPVI) --Hillary Clinton faces a big challenge Tuesday. Can she make a stronger-than-expected showing in Bernie Sanders' backyard and regain some of the momentum lost after her narrow Iowa victory.
Sanders has a comfortable lead in most polls, but New Hampshire voters are known for going their own way when it comes time to enter the voting booth.
Thousands braved the weather to see Donald Trump at a rally Monday night in downtown Manchester's Verizon Wireless arena.
We spoke to some of them on their way in.
"It's one thing to hear all the ads and see what everybody is saying negative, but we'll see what the actual message is," Paul Grenier of Exeter, New Hampshire said.
"I'm actually a registered Democrat, so I won't be voting for Trump tomorrow, but, you know, he could advance to the general [election,]" Sarah Duval of Manchester, New Hampshire said.
Outside the arena, Trump protesters were making their presence known.
"We don't' want to fear and hate in the White House. I think Donald Trump does a very good job of exploiting and capitalizing on people's fears," protester Katy Gowen said.
The big question Tuesday: which Republican will make the best showing for second place? Ted Cruz, Marco Rubio and Jeb Bush have been trying to woo voters, while New Jersey Governor Chris Christie faces a big decision if he can't crack the top three or four.
And then there's former New York mayor Michael Bloomberg, who told the Financial Times he is definitely considering an independent run for president.
The voting in New Hampshire will actually begin at midnight in three small towns, Dixville Notch, Hart's Location and Millsfield.
Around the rest of the state, they're expecting a record turnout, snow or no snow.
