John Sununu easily won Tuesday’s New Hampshire Republican Senate primary, boosting the GOP’s chances of maintaining control of the chamber in November. He claimed over 69 percent of the vote over former Massachusetts Sen. Scott Brown in the primary.
No stranger to elective office in the Granite State, Sununu served three terms in the U.S. House of Representatives from 1997-2003 and one term in the Senate from 2003 through 2009.
A poll taken shortly before the primary sponsored by the National Republican Senatorial Committee (NRSC) showed Sununu narrowly leading the Democrat nominee, Rep. Chris Pappas, with 37 percent to Pappas’ 36 percent.
The NRSC said in a statement that, “Poll after poll shows that Granite Staters are fed up with Party Line Pappas being a rubber stamp for Democrats’ radical agenda and they are ready to elect John Sununu in November.”
Pappas won the primary over a Democratic Socialist of America (DSA)-backed candidate, Karishma Manzur, and needed a late endorsement from failed presidential candidate Kamala Harris to push him over the finish line.

In remarks following his primary victory, Sununu pledged to, “stand up for the people of New Hampshire every single day,” and said his campaign is centered on affordability, independent leadership, and putting New Hampshire first.
