Among students planning to vote for Sanders in the New Hampshire primary, 73 percent describe themselves as "very liberal", while 80 percent of Buttigieg voters identify as "centrist" or "left-leaning".
Only Sen. Amy Klobuchar, D-Minn., raised her hand, though she appeared to do it reluctantly.
The news amplified the importance of the New Hampshire vote and the candidates know it.
They also hoped that the Secret Service restrictions accompanying his Manchester rally would clog up the state's biggest city on the eve of the Democratic primary, hampering candidates and voters from getting around. These are much simpler than caucuses - hours-long meetings with multiple rounds of balloting.
Out in the cold on Tuesday morning volunteers and voters alike made their way to polling stations across New Hampshire to vote for the Democrat that will eventually go on to challenge President Donald J. Trump for the White House.
The Sunrise Movement, which has endorsed Sanders, is making a major push for him in New Hampshire-knocking on doors and logging thousands of calls for the senator.
The contest in New Hampshire has taken on added effect in the aftermath of a split vote in last week's Iowa caucuses that were remembered mostly for the agonizingly slow release of the final outcome that was linked to a wrongly coded app used in collecting vote totals from throughout the farm state. The goal for presidential candidates is to win early-voting states and create name recognition and a sense of momentum, as well as pick up their first delegates.

Looming over the primary, Trump himself jetted in to New Hampshire Monday night aiming to steal the limelight with a large Manchester rally.
Klobuchar is also trying to walk into the opening that Sanders' surge and Biden's fall creates for a moderate alternative. Biden said. "And that's the place where I think I'm in the strongest position". He's running negative ads against Buttigieg's experience and hitting out at Sanders with warnings that he will have a tough time beating Trump with the label "Democratic Socialist". Elizabeth Warren, who faces the prospect of an embarrassing defeatin a state that borders her home of MA. Biden has earned the overwhelming share of endorsements from elected officials across the nation as party leaders seek a relatively "safe" nominee to run against Trump.
"You get knocked down", she said. Bernie Sanders and former South Bend, Indiana Mayor Pete Buttigieg. "I just don't agree with him on a lot of things", Klobuchar said.
Perhaps anticipating another poor showing, Biden announced Tuesday he will skip his New Hampshire election night party, fleeing on a private jet to SC, where he will address his abandoned supporters via live stream.
It's still possible-maybe even still likely-that Biden will recover his front-runner status in the SC primary later this month, where he hopes to demonstrate an enormous lead among African American voters without whom a Democratic nominee can not win in November.
Biden - and the Democratic Party's establishment wing - may have the most to lose on Tuesday should the former two-term vice president underperform in a second consecutive primary election. Bernie Sanders, a self-declared democratic socialist from Vermont, who is leading in New Hampshire polls. Asked if she'd done enough to differentiate herself from Sanders, Warren said there were key differences that were obvious to voters. All the top candidates insist they have the funds to continue through Super Tuesday, when the race moves to expensive states like California and Texas.
Superdelegates are high-profile members of the Democratic Party who automatically get a vote at the convention.
