Trump Makes New Endorsement
President Donald Trump has officially endorsed former New Hampshire senator John E. Sununu in the state’s Republican U.S. Senate primary, giving Sununu a major boost in one of the most closely watched races of the 2026 election cycle.
In a Truth Social post on Sunday, President Trump praised Sununu’s support among New Hampshire leaders and Republicans in Washington, calling him a proven conservative who will fight for the America First agenda. Trump said Sununu has the backing of respected state figures and Senate Republicans and gave him his “complete and total endorsement.”
The endorsement represents a setback for Sununu’s primary rival, Scott Brown, a former U.S. senator from Massachusetts who later served as ambassador to New Zealand during President Trump’s first administration.
Recent polling already shows Sununu with a commanding advantage. A University of New Hampshire survey released last month found Sununu leading Brown by a wide margin among likely Republican primary voters, with Sununu receiving 48 percent support compared to Brown’s 25 percent.
Brown entered the New Hampshire race in June, despite previously representing Massachusetts in the U.S. Senate. Democrats have criticized his candidacy by questioning his ties to the state, attempting to frame him as an outsider seeking office in New Hampshire after serving elsewhere.
Republican leaders say the president’s endorsement highlights the importance of the race as the GOP looks to expand its Senate majority. Party officials have indicated the seat is a top priority heading into November, with national resources expected to be deployed.
The winner of the Republican primary is likely to face Democratic Rep. Chris Pappas in the general election. The seat is currently held by Sen. Jeanne Shaheen, who has announced she will not seek reelection. Election analysts currently rate the race as leaning Democratic.
Recent polling indicates Republicans could be more competitive in the general election with Sununu at the top of the ticket. The University of New Hampshire survey found Sununu behind Pappas by five points in a direct matchup, while Brown lags well into double-digit territory.
With President Trump’s endorsement now secured and polling momentum on his side, Sununu is emerging as the clear Republican frontrunner in a Senate race that could play a key role in determining control of Congress.
