Rebecca Bennett has won a high-stakes Democratic Party primary in the US state of New Jersey, setting up a contest against Republican Tom Kean Jr, backed by President Donald Trump, for one of the most competitive seats in the upcoming midterm elections.

Bennett, a former US Navy helicopter pilot, defeated three Democratic rivals in New Jersey’s 7th Congressional District, securing about 47.2 percent of the vote, according to projected results on Tuesday.

Her nearest competitor, Tina Shah, received 20.2 percent.

Kean and Bennett will now square off in November for a seat that has changed party hands twice within the past eight years and ranks as a key target for Democrats hoping to capture the House of Representatives.

Independent analysts rate the contest as a toss-up.

The race has attracted heightened attention because of Kean’s prolonged absence from Congress.

The Republican incumbent has missed more than 100 House votes since early March due to an undisclosed illness.

Despite his absence, Kean ran unopposed in the Republican primary with Trump’s backing.

Kean said on Tuesday that he remained focused on his recovery and expected to return to in-person work within weeks.

Hours before polls closed, Kean released a statement promising greater transparency about his health while suggesting his return to in-person work could take longer than previously anticipated.

On May 21, he said he expected to be back within “a couple of weeks”.

“Right now, I am focused on my recovery and, under the advice of healthcare professionals, I will transition from virtual to in-person work within a matter of weeks,” Kean had said.

Bennett targets cost of living, Kean’s absence

At an election night gathering in Somerville, New Jersey, Bennett sharply criticised Kean’s record and absence from Washington.

“You are failing us, and you do not deserve to represent us in Washington,” she told supporters, calling the congressman a “coward”.

Bennett built her campaign around her military service and economic issues, arguing that higher grocery and gasoline prices during the US-Israel war on Iran, combined with Trump’s tariffs, were squeezing working families.

Democrats have increasingly focused on the conflict’s economic impact, with higher energy costs contributing to inflation and broader cost-of-living pressures across the country.

The 7th Congressional District, which includes suburban communities, farm towns and Trump’s golf club in Bedminster, has emerged as one of New Jersey’s key battlegrounds.

The seat has changed hands repeatedly in recent election cycles, with Democrat Tom Malinowski defeating Republican Leonard Lance in 2018 before Kean unseated Malinowski in 2022.

Bennett’s victory over Tina Shah, Brian Varela and Michael Roth now sets up a high-stakes general election contest in a district both parties consider crucial to their House ambitions.

Kean, 57, is the scion of a storied New Jersey political family.

His father, Thomas Kean, served two terms as governor and later chaired the 9/11 Commission, a panel set up in 2002 to investigate the circumstances surrounding the September 11, 2001, attacks in the US. He is also a descendant of William Livingston, New Jersey’s first governor.

The Republican congressman will also enter the race with the backing of Trump, who reiterated his support on the eve of the primary, despite Kean’s prolonged absence from Washington.

“Tom Kean has my Complete and Total Endorsement for Re-Election,” Trump wrote on social media, adding: “HE WILL NEVER LET YOU DOWN!”

Voters in the district have ousted incumbents in recent midterm elections, making the race one of the most competitive House contests in New Jersey.

Elsewhere in New Jersey, Analilia Mejia won the Democratic nomination in the 11th Congressional District, while LaMonica McIver secured the Democratic nomination in the 10th Congressional District.
