Donald Trump endorses John Sununu for New Hampshire Senate primary

Donald Trump is utilizing his political influence to support former Senator John Sununu in the upcoming New Hampshire GOP Senate primary. Sununu is running to return to the U.S. Senate, competing against former ambassador to New Zealand Scott Brown.

Trump endorsed Sununu in February, describing him as an ‘American First patriot’ with strong backing among conservative leaders. This endorsement is part of Trump’s broader strategy in the 2026 midterm cycle, where he has maintained a 97% success rate with his endorsed candidates. The choice of Sununu over Brown is seen as a move to ensure general election viability in a state that has historically been difficult for Republicans to hold.

While Brown has framed his campaign as an independent, grassroots effort despite previous ties to Trump, Sununu relies on his local heritage and established institutional support in New Hampshire.
