Bolducs victory is a blow to Republican establishment leaders, including Gov. Chris Sununu, who preferred Chuck Morse to be their nominee against Democratic Sen. Maggie Hassan.
Don Bolduc, a self-styled political outsider, has won New Hampshires Republican U.S. Senate nomination, NBC News projects, overcoming a push by the GOP establishment to elevate state Senate President Chuck Morse.
Bolduc will face Democratic Sen. Maggie Hassan, who was renominated easily Tuesday, in whats expected to be one of the falls marquee matchups.
With less than two months until the general election, Hassan starts with a commanding cash advantage. She reported $7.3 million on hand at the end of August, according to campaign finance reports. Bolduc reported $84,000.
The primary the last major contest before Novembers midterm elections had become a national battleground, with outside money from both parties flowing into a state that could determine partisan control of the Senate.
Although there were other candidates, the GOP battle boiled down to a clash between insider and outsider. Morse, a longtime state legislator, had an endorsement from Gov. Chris Sununu and more than $4 million in air cover from a group with ties to establishment Republicans in Washington, D.C.
Bolduc, a retired Army brigadier general, has more of a connection to the right-wing base. He has a reputation for incendiary rhetoric and for promoting 2020 election conspiracies. Despite his sparsely funded campaign, Bolduc had a Democratic group doing his dirty work, spending more than $3 million during the primary to tag Morse as a yes-man for Senate GOP Leader Mitch McConnell, a villainous figure to many Republicans loyal to former President Donald Trump. Polls in the final weeks showed Bolduc ahead comfortably.
"Our campaign overcame the odds and millions of dollars in spending from outside special interest groups because we built a true bottom-up grassroots campaign," Bolduc said in a statement.

Hassan, in a statement, called Bolduc "simply too extreme" for the state.
"This campaign will be a clear contrast between my record of delivering for the people of New Hampshire and Don Bolducs radical, backward- looking agenda," she said.
