But he seemed as confident as ever today, and if this is possible, even more confident. Thank you. And the democrats, Hillary Clinton traveling to Flint, Michigan, standing with those suffering from the water crisis. And Bernie sanders, all smiles in New Hampshire, fresh off his comedy turn in New York. Cecilia Vega, following the democrats from the start. Reporter: Bernie sanders, today, feeling confident. The Vermont senator, packing in the crowds, and packing in the punches. The most important foreign policy issue in the modern history of this country was the war in Iraq. I was right on that issue. Hillary Clinton was wrong! Reporter: Two days until New Hampshire, voters make their decision and it is now a fight to the finish. But the real question for Bernie sanders right now is not whether he can win here in New Hampshire, but whether he can carry all of this momentum beyond his backyard. Hillary Clinton trailing by double digits in most polls here, instead spending her day in Flint, Michigan, talking about that water crisis. What happened in Flint is immoral. Reporter: Leaving her most famous surrogate back in New Hampshire to make the case for her. Republicans have tried way harder, way longer to beat her than they did me because they are way scareder of her than they were of me. Reporter: But overnight, a different kind of face-off. I am so sick of the 1% getting this preferential treatment. Reporter: Sanders coming face to face with his "Snl" doppelganger, Larry David. Sounds like socialism to me! Democratic socialism. What's the difference? Huge difference. Reporter: A lot of laughs last night. Clinton advisers do not expect her to win this state. If Hillary Clinton is hoping to tap into the undecided vote, at the last minute, polls show 21% of voters in New Hampshire have yet to make up their mind. Tom? The expectations game well under way. Cecelia, thank you. And stay with ABC news for the New Hampshire primary, I'm back there tomorrow, following the republicans.
