Winners and runners-up -- Presidential results

The New Hampshire primary is the first in a series of nationwide party primary elections and the second party contest (the first being the Iowa caucuses) held in the United States every four years as part of the process of choosing the delegates to the Democratic and Republican national conventions which choose the party nominees for the presidential elections to be held the subsequent November. Although only a few delegates are chosen in the New Hampshire primary, its real importance comes from the massive media coverage it receives (along with the first caucus in Iowa). Spurred by the events of the 1968 election, reforms that began with the 1972 election elevated the two states' importance to the overall election, and began to receive as much media attention as all of the other state contests combined. Examples of this extraordinary coverage have been seen on the campuses of Dartmouth College and Saint Anselm College, as the colleges have held multiple national debates and have attracted media outlets like NPR, Fox News, CNN, NBC, and ABC. The publicity and momentum can be enormous from a decisive win by a frontrunner, or better-than-expected result in the New Hampshire primary. The upset or weak showing by a front-runner changes the calculus of national politics in a matter of hours, as happened in 1952 (D), 1968 (D), 1980 (R), and 2008 (D). Since 1952, the primary has been a major testing ground for candidates for both the Republican and Democratic nominations. Candidates who do poorly frequently drop out, while lesser-known, underfunded candidates who excel in New Hampshire can become serious contenders, garnering large amounts of media attention and campaign funding. Crucially, the New Hampshire primary is not a closed primary, where voter participation is limited by voters' past or recent party registration. Instead, New Hampshire enables any voter who has been undeclared, or re-registers as undeclared (not registered with any party) to vote in either party's primary. Candidates who do well in the state are seen as having a strong appeal to independents - who account for as much as 41% of the electorate. A strong performance in New Hampshire is seen as a bellwether for how well a candidate can do in a general election, given their appeal to less partisan voters who sometimes flood that party's primary, if they want to participate at all.
