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.

This page focuses on New Hampshire's United States Senate Republican primary. For more in-depth information on the state's Democratic primary and the general election, see the following pages:

Polls

Polls are conducted with a variety of methodologies and have margins of error or credibility intervals.[3] The Pew Research Center wrote, "A margin of error of plus or minus 3 percentage points at the 95% confidence level means that if we fielded the same survey 100 times, we would expect the result to be within 3 percentage points of the true population value 95 of those times."[4] For tips on reading polls from FiveThirtyEight, click here.

Below we provide results for polls from a wide variety of sources, including media outlets, social media, campaigns, and aggregation websites, when available. We only report polls for which we can find a margin of error or credibility interval. Know of something we're missing? Click here to let us know.
