President Donald Trump endorsed former Sen. John Sununu for the U.S. Senate seat in New Hampshire on Truth Social on Sunday afternoon.

Sununu, the older brother of former Gov. Chris Sununu, is competing for the GOP nomination against former U.S. Ambassador Scott Brown. The primary winner will face Rep. Chris Pappas in the general election to replace retiring Sen. Jeanne Shaheen.

According to the Washington Examiner, Trump's endorsement described Sununu as a supporter of an America First agenda. The announcement has generated reactions across the political spectrum regarding the New Hampshire Senate race.

Trump’s Endorsement Shakes Up Primary Dynamics

Trump’s statement on Truth Social didn’t hold back in praising Sununu’s credentials. “It is my Great Honor to endorse America First Patriot, John E. Sununu, who is running to represent the beautiful State of New Hampshire in the U.S. Senate,” Trump declared. His words carry weight, especially among voters tired of establishment flip-flopping.

This move is seen as a direct rebuff to Scott Brown, who, despite the snub, vows to stay in the race. Republican leaders, including the National Republican Senatorial Committee and the Senate Leadership Fund, are rallying behind Sununu, believing he’s the stronger bet against Pappas. Polling, as noted by Senate Majority Leader John Thune last December, seems to back that up.

Thune’s earlier comments pointed to electability as the driving factor. Sununu’s camp has also gained traction with endorsements from influential figures, signaling a unified front to reclaim the seat. For too long, New Hampshire has been a tough nut to crack for Republicans, and this could be the turning point.

Sununu’s Shift and GOP Strategy

Sununu wasn’t always on board with Trump, having voiced criticism in the past. Yet, in November, he positioned himself as ready to work alongside the President if elected. This pivot shows a pragmatic approach, aligning with voters who want results over rhetoric.

“We need someone who can be an effective advocate with President Trump in this White House, and there’s absolutely no question I will be that person,” Sununu affirmed. His emphasis on being no mere “rubber stamp” resonates with those skeptical of blind loyalty. It’s a smart play in a state that values independence.

The Republican National Committee is equally bullish, with spokeswoman Kristen Cianci noting the race’s importance. Trump’s involvement underscores that this Senate seat is a priority, and GOP turnout in November could be fierce. After years of Democratic dominance in New Hampshire Senate races, the hunger for a win is palpable.

Democratic Pushback and Election Outlook

On the flip side, Democrats aren’t sitting idly by. The Democratic Senatorial Campaign Committee fired shots at Sununu’s record, claiming he’s out of touch with everyday voters. Their spokeswoman predicted another GOP loss in 2026, pointing to a decade-long drought for Republicans in these races.

That kind of smugness from the left only fuels the fire for conservatives itching to prove them wrong. The DSCC’s dismissal of Sununu ignores the groundswell of support Trump’s endorsement can ignite. It’s the same tired playbook—underestimate the resolve of America First voters at your peril.

Scott Brown, undeterred by the endorsement snub, remains committed to his campaign. His focus on serving rather than career-building could still appeal to those wary of party-line picks. But with Trump’s backing tilting the scales, his path looks steeper.

What’s Next for New Hampshire Voters

The primary’s outcome will set the tone for a bruising general election against Pappas. Sununu’s priorities, like bolstering the economy and supporting law enforcement, align with core conservative values often drowned out by progressive noise. This race could be a referendum on whether New Hampshire wants practical governance or more of the same.

Trump’s influence here isn’t just a footnote; it’s a call to action for voters fed up with woke policies creeping into every corner of life.

If Sununu can harness this momentum, the GOP might finally flip a seat that’s eluded them for too long. November will tell if the America First agenda finds a home in the Granite State.
