## Early life, education, and business career
Sununu grew up in Salem, New Hampshire, and graduated from Salem High School in 1982[1](https://history.house.gov/People/Detail/22472). His education included mechanical engineering degrees, both a bachelor's and a master's, from the [Massachusetts Institute of Technology](https://www.edgepedia.org/massachusetts-institute-of-technology), and he completed a [Master of Business Administration](https://www.edgepedia.org/master-of-business-administration) at [Harvard Business School](https://www.edgepedia.org/harvard-business-school) in 1991.[3](https://www.bostonscientific.com/en-US/about-us/leadership/john-sununu.html) Before entering politics he worked in high technology, engineering, consulting, and manufacturing, serving as chief financial officer and director of operations at Teletrol Systems, a Manchester, New Hampshire manufacturer of building control systems[3](https://www.bostonscientific.com/en-US/about-us/leadership/john-sununu.html) • [7](https://www.sununusenator.com/about).
Politics ran in the family. His father, [John H. Sununu](https://www.edgepedia.org/john-h-sununu), was a former governor of New Hampshire and White House chief of staff, and his brother [Chris Sununu](https://www.edgepedia.org/chris-sununu) later served four terms as governor[2](https://apnews.com/article/e806398a52e3878c5df164507c8e0cda). His mother, Nancy, chaired the Salem School Board[7](https://www.sununusenator.com/about).
## House of Representatives, 1997–2003
Sununu won a seven-way Republican primary in 1996 for New Hampshire's 1st District by fewer than 500 votes[4](https://rollcall.com/2008/05/09/sununu-shrugs-off-polls-predicts-win/). He then served three terms in the House, from January 3, 1997 to January 3, 2003, where he was vice chairman of the Budget Committee and a member of the Appropriations Committee[1](https://history.house.gov/People/Detail/22472) • [3](https://www.bostonscientific.com/en-US/about-us/leadership/john-sununu.html).
His legislative record from those years includes the Internet Tax Freedom Act, which his campaign site describes as a ban on taxes on internet access, the Survivors Benefit Act, and the New England Wilderness Act[3](https://www.bostonscientific.com/en-US/about-us/leadership/john-sununu.html) • [7](https://www.sununusenator.com/about).
## United States Senate, 2003–2009
**The 2002 race.** Sununu did not seek House reelection in 2002 and instead challenged incumbent Republican Senator Bob Smith in the primary, a challenge he won with the support of many Senate Republicans[1](https://history.house.gov/People/Detail/22472) • [4](https://rollcall.com/2008/05/09/sununu-shrugs-off-polls-predicts-win/). In the general election he defeated Jeanne Shaheen, the state's popular sitting governor, by roughly 20,000 votes, about 4 percentage points, in a year that favored Republicans nationally[5](https://transcripts.cnn.com/show/sitroom/date/2008-10-22/segment/01) • [8](https://www.thecrimson.com/article/2008/11/4/shaheen-wins-nh-senate-seat-former/). He entered the Senate at age 38 and was the chamber's youngest member throughout his term[2](https://apnews.com/article/e806398a52e3878c5df164507c8e0cda).
In the Senate he served on the Committees on Banking, Commerce, Finance, and Foreign Relations, and was appointed the Congressional Representative to the [United Nations General Assembly](https://www.edgepedia.org/united-nations-general-assembly)[3](https://www.bostonscientific.com/en-US/about-us/leadership/john-sununu.html). He compiled a fiscal record his campaign describes as opposing tax increases and targeting government waste[7](https://www.sununusenator.com/about).
**The 2008 defeat.** Shaheen, who had resigned from a Harvard Institute of Politics post in 2007 to run again, reprised the 2002 contest[8](https://www.thecrimson.com/article/2008/11/4/shaheen-wins-nh-senate-seat-former/). A hostile national climate for Republicans shaped the contest: across 35 public surveys conducted between March 2007 and late October 2008, Sununu was behind in every one except a single poll, and although Shaheen's advantage shrank, his own numbers remained stuck in the low 40s.[9](https://rollcall.com/2008/12/01/new-hampshire-senate-the-polls-didnt-lie/) On November 4, 2008, Shaheen won 358,438 votes (51.59%) to Sununu's 314,403 (45.25%)[6](https://uselectionatlas.org/RESULTS/state.php?class=2&elect=0&f=0&fips=33&off=3&year=2008). Campaign spending was nearly even, with the FEC reporting $8,010,010 raised by the Sununu campaign and $8,208,542 by Shaheen's[10](https://www.fec.gov/press/press2009/05282009Party/9_PartyActSenate.pdf). Sununu left office on January 3, 2009[1](https://history.house.gov/People/Detail/22472).
## Post-Senate career
After leaving the Senate, Sununu moved into private-sector and corporate governance work. He has been a director of [Boston Scientific](https://www.edgepedia.org/boston-scientific), a medical device manufacturer, since April 2009, and has also served as a director of BlueRiver Acquisition Corp., a former director of Time Warner Cable Inc., and a Council Member of Lloyd's of London[3](https://www.bostonscientific.com/en-US/about-us/leadership/john-sununu.html). His campaign biography adds teaching at [Saint Anselm College](https://www.edgepedia.org/saint-anselm-college) in Manchester and chairmanship of the board of Waterville Valley Ski Resort[7](https://www.sununusenator.com/about).
## Return to politics: the 2026 Senate campaign
On October 22, 2025, Sununu announced a campaign for the Senate seat being vacated by Jeanne Shaheen, who defeated him in 2008 and is retiring[2](https://apnews.com/article/e806398a52e3878c5df164507c8e0cda) • [11](https://www.axios.com/2025/10/22/john-sununu-senate-bid-new-hampshire-2026-election). The announcement was welcomed by Senate Republican leaders: Majority Leader John Thune had urged him to run, the [Senate Leadership Fund](https://www.edgepedia.org/senate-leadership-fund) said the bid "expands the Senate map and puts the Granite State in play for Republicans," and NRSC Chair Tim Scott called the committee "all-in" for Sununu, hosting a Washington fundraiser for his campaign[2](https://apnews.com/article/e806398a52e3878c5df164507c8e0cda) • [11](https://www.axios.com/2025/10/22/john-sununu-senate-bid-new-hampshire-2026-election) • [12](https://www.axios.com/2025/10/24/nrsc-john-sununu-dc-fundraiser-new-hampshire-senate).
In the November 2026 general election he faces Representative Chris Pappas, the front-runner for the Democratic nomination[2](https://apnews.com/article/e806398a52e3878c5df164507c8e0cda). The Republican primary itself paired two former senators, with [Scott Brown](https://www.edgepedia.org/scott-brown-politician), previously a senator from Massachusetts, running since June in an eight-candidate field; by September 2026 Sununu led Brown in both polls and fundraising[13](https://apnews.com/article/479b5148d8cdd7399d1534dbe666ffba). Sununu's family name remains a political asset and a point of confusion: debate moderators and voters have mistaken him for his brother Chris or his father[13](https://apnews.com/article/479b5148d8cdd7399d1534dbe666ffba). His relationship with President Trump is complicated by history; in 2016 he published an op-ed in *The Union-Leader* headlined "Donald Trump is a Loser," and Trump holds his family in contempt, according to *Time* reporting on the race[14](https://time.com/7357434/democrats-2026-elections-senate-races-donald-trump-texas-maine-michigan/).
