Heading into the election, the incumbent is Jeanne Shaheen (Democrat), who was first elected in 2008.

A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. New Hampshire uses a semi-closed primary system. Unaffiliated voters may vote in the primary, but in order to do so, they have to choose a party before voting. This changes their status from unaffiliated to affiliated with that party unless they fill out a card to return to undeclared status.[1][2]

For information about which offices are nominated via primary election, see this article.
