Voters, candidates, reporters and snow filled New Hampshire Tuesday as the state held its 2016 primary election in the ongoing presidential race. More than 500,000 people were expected to cast ballots throughout the day, with polls closing in most locations at 7 p.m. EST, WBZ reported. The results will come out soon after.

Later in the night, local news station WMUR will go live here at 5 and 7:30 p.m. EST. C-SPAN's broadcast will start at 8 p.m. EST here and feature viewer calls as well as candidate speeches.

New Hampshire is the first formal primary election in the nation, following the Iowa caucuses last week. About 44 percent of voters in the Granite State are undeclared, or independent, so Tuesday night could produce some surprises.

"Never have we gone this far, this long, with so many people unclear about their candidate, their choice for president,'' state Republican consultant Michael Dennehy told the Chicago Tribune.

Heading into Tuesday's election, real estate tycoon Donald Trump was leading the pack of Republican candidates with about 31 percent of the vote, according to data averaged by Real Clear Politics. Florida Sen. Marco Rubio and former Ohio Gov. John Kasich were essentially tied for second place with 14 percent, and former Florida Gov. Jeb Bush and Texas Sen. Ted Cruz were fighting for third with 12 percent.

On the Democratic side, Vermont Sen. Bernie Sanders was leading former Secretary of State Hillary Clinton by about 13 percentage points. Clinton narrowly eked out a win last week in Iowa.

"Sanders has advantages, not just geographically and ideologically," Dante Scala, a political scientist from the University of New Hampshire, told the Los Angeles Times. "Hillary Clinton, whose husband was the comeback kid because of those white working class voters — Clinton may lose them and lose them handily to the most progressive senator in America, which would be remarkable."
