The New Hampshire presidential primary is set for Tuesday, with the election considered a big test as Super Tuesday looms on March 3.

New Hampshire Secretary of State Bill Gardner expects 420,000 voters consisting of 292,000 Democratic ballots and 128,000 Republican ballots. Polls must open at 11 a.m. or earlier and cannot close before 7:00 p.m, according to

While Nevada and South Carolina also have their primaries before Super Tuesday, New Hampshire has historically drawn the most attention. The last time the Republican nominee failed to win New Hampshire was in 2000, when John McCain earned a landslide victory over George W. Bush. But in 2008 and 2016, the Democratic nominee failed to win New Hampshire.

There is plenty to know about the first primary of the 2020 election.

  • New Hampshire state law says that the primary should always be held on the second Tuesday in March, but this can be changed by the Secretary of State, with the primary generally taking place one week after the Iowa caucus in recent election cycles.

  • The tradition of New Hampshire as the first state primary dates back to 1920.

  • New Hampshire has a semi-open primary, where undeclared voters can vote in either party’s primary.

  • Voters who register as Republicans or Democrats must participate in their own party’s primary and are not allowed to switch sides.

  • The Democratic primary will feature the following candidates: former Vice President Joe Biden, Vermont Sen. Bernie Sanders, Massachusetts Sen. Elizabeth Warren, Minnesota Sen. Amy Klobuchar, Indiana Mayor Pete Buttigieg, California businessman Tom Steyer, Hawaii Rep. Tulsi Gabbard and tech entrepreneur Andrew Yang. Former New York Mayor Michael Bloomberg is not on the ballot.

  • Most polls show Sanders in the lead, but Buttigieg has been catching up. Buttigieg and Sanders had the strongest showing in the Iowa caucuses.

  • The Republican primary will feature incumbent President Donald Trump and former Massachusetts Gov. Bill Weld. Former Rep. Joe Walsh dropped out of the race on Friday.

  • Weld, who was a Libertarian running mate to former New Mexico Gov. Gary Johnson, hopes to pull off an upset win in New Hampshire, saying the feat is “doable” for his campaign.

  • Sanders won the primary in 2016 on the Democratic side, with Trump winning the Republican contest.

  • Former President Richard Nixon won the New Hampshire primary in 1960, 1968 and 1972, the most of any candidate.
