Results of the 2010 United States House of Representatives elections in New Hampshire by district:

District 1


Democratic incumbent Carol Shea-Porter was defeated by Republican nominee and former Manchester Mayor Frank Guinta on November 2, 2010.

This district covers the southeastern and eastern portions of New Hampshire, consisting of three general areas: Greater Manchester, the Seacoast and the Lakes Region. It includes all of Carroll and Strafford counties, all but three towns of Rockingham County and all but two towns of Belknap County, as well as a small portion of Hillsborough County, and one town in Merrimack County.

District 2


Democratic candidate Ann McLane Kuster was defeated by Republican nominee and former Congressman Charles Bass on November 2, 2010.

This was an open seat. Candidates running were Democratic nominee Ann McLane Kuster, Republican nominee Charles Bass, Libertarian nominee Howard Wilson, and Independent candidate Tim vanBlommesteyn.

In February 2009, Republican U.S. Senator Judd Gregg was briefly nominated to be President Barack Obama's Secretary of Commerce, but withdrew. Gregg announced after withdrawing his nomination that he would not run for re-election, leaving the seat open. Democratic incumbent Paul Hodes had announced his candidacy for the seat while Gregg had been nominated but had not yet withdrawn.

Concord attorney Ann McLane Kuster and Katrina Swett, faced off in the Democratic primary. (Two other candidates dropped out before the filing deadline in June 2010: State Representative John DeJoie and former Democratic gubernatorial candidate Mark Fernald.) Kuster was the eventual victor, 69-31.

On the Republican side, former state Representative Bob Giuda declared his candidacy for the seat. The 2008 Republican nominee for this seat, Jennifer Horn, announced her intentions to run a second time on October 7, 2009. Former six-term Congressman Charles Bass formed an exploratory committee to run for this seat on October 1, 2009 and later formally filed. In the resultant Republican primary, Charlie Bass narrowly defeated Jennifer Horn, with Giuda far behind.

This district consists of the western and northern portions of the state, including all of Cheshire, Coos, Grafton, and Sullivan counties as well as almost all of Merrimack and Hillsborough counties plus three towns in Rockingham County and two towns in Belknap County.
