BOSTON (AP) — Massachusetts Democrats maintained their hold on the state’s congressional delegation Tuesday, with four incumbents fending off Republican and independent challengers and the other five coming to two-year terms without opponents.

Republicans and independents have struggled to win congressional seats in the overwhelmingly Democratic state. No Republican has been elected to the Massachusetts House of Representatives in nearly three decades.

The five Democrats who ran unopposed: Jake Auchincloss, Katherine Clark, Seth Moulton, Ayanna Pressley and Lori Trahan,

Democrat Richard Neal re-elected in 1st Congressional District

Longtime Democratic U.S. Rep. Richard Neal won re-election, defeating independent Nadia Milleron.

Neal was first elected to Congress in 1988 to represent the 1st Congressional District, the largest in the state in the western and central regions. He is the top Democrat on the powerful House Ways and Means Committee.

Neal said his priorities include “fairer taxes, affordable and accessible health care, fighting climate change, preserving Social Security, and much more.”

Milleron, the niece of consumer rights advocate Ralph Nader, said she was pushed to run for Congress after her daughter’s death in 2019 in the second Boeing 737 Max crash, in Ethiopia. Milleron pushed for passage of a 2020 law requiring the Federal Aviation Administration to change how it certifies new planes.

Democrat James McGovern re-elected in 2nd Congressional District

Democrat James McGovern was re-elected to a seat in the Massachusetts House of Representatives, fending off a challenge from independent Cornelius Shea.

McGovern, who was first elected to Congress in 1996, represents the state’s 2nd congressional district, which includes Worcester, the state’s second-largest city.

Throughout his tenure in Congress, McGovern presented himself as a human rights defenderincluding in Tibet in China, campaign finance reform and social justice.

McGovern has also been a vigorous critic of the Republican Party under former President Donald Trump.

Shea, a 20-year Navy veteran, worked for AT&T before becoming a public school teacher in Worcester. In a campaign statement, he cited illegal immigration, drug overdoses, terrorism and health care costs as his top concerns.

Democrat Stephen Lynch re-elected in the 8th Congressional District

Democrat Stephen Lynch was re-elected to the U.S. House of Representatives seat he has held for more than two decades, fending off efforts by Republican Robert Burke to unseat him.

Lynch has held the state’s 8th Congressional District, which includes parts of Boston, since he was elected following the death of Rep. Joseph Moakley in 2001.

The former ironworker is a member of the Financial Services Committee and is the top Democrat on the Subcommittee on Digital Assets, Financial Technology and Inclusion.

Burke, who describes himself as an amateur journalist and videographer, had said he was speaking to independent voters, both Democrats and Republicans, who are tired of what he called the “Kamala-Lynch open border.” In a campaign statement, he said state money spent on migrants should have gone “to helping our children, our roads, our schools and our veterans.”

Democrat Bill Keating re-elected in 9th Congressional District

Democrat Bill Keating was re-elected to the U.S. House of Representatives, overcoming a challenge from Republican Dan Sullivan.

Keating, who was first elected to the House in 2010, represents the state’s 9th Congressional District, which includes the South Shore, South Coast, Cape Cod and the islands of Martha’s Vineyard and Nantucket.

Keating currently serves on the House Foreign Affairs and Armed Services Committees.

Keating pushed for federal funding to help replace the two bridges spanning the Cape Cod Canal. He also championed legislation that would fund care for stranded turtles that wash up on Cape Cod and elsewhere.

Sullivan, a nurse, said he could bring a fresh perspective to Washington. Sullivan said he supports prosecuting drug dealers while providing treatment programs for addicts. He also supports securing borders, enforcing immigration laws and prioritizing legal immigration for those with skills in science, technology, engineering and mathematics.
