The Winner

Rep. Lori Trahan (D-MA) won a fifth term in Massachusetts’ 3rd Congressional District on Tuesday, Nov. 3, defeating Republican Gary Grossi 67.2% to 30.3%. Unenrolled candidate Dennis R. Conlon took 2.5%. With more than 99% of votes counted, Trahan led Grossi 173,329 to 78,297, a margin of 95,032 votes, according to Associated Press election results. The AP called the race at 10:18 p.m. Eastern Time on election night. ​

Trahan returns to a House where her party now holds the majority after Democrats won control of the chamber. She serves on the Energy and Commerce Committee and its subcommittees on health, oversight and investigations, and commerce, manufacturing and trade.

The Race

Trahan’s 37-point margin topped her result in 2022, when she beat Republican Dean Tran 63.5% to 36.4%, according to Ballotpedia’s race overview. She had no Republican opponent in 2024. Both nominees ran unopposed in their Tuesday, Sept. 1 primaries. Grossi, an Army veteran, has worked as a psychiatric and substance abuse nurse at Veterans Affairs hospitals.

Forecasters expected a lopsided result. Cook Political Report and Inside Elections rated the race Solid Democratic, and Sabato’s Crystal Ball rated it Safe Democratic.

The district includes the cities of Lowell, Lawrence, Haverhill, Methuen and Marlborough, along with towns stretching west into northern Worcester County, according to the Massachusetts General Laws’ district boundaries. It is home to about 785,400 people, with a median household income of about $99,700. About 40% of adults hold a bachelor’s degree or higher, and about 10.3% of residents live below the poverty line. The population is about 62.2% white, 22.9% Hispanic, 8.3% Asian and 4.6% Black.

What’s Next

Trahan’s new term begins Sunday, Jan. 3. Before then, Congress faces a Friday, Dec. 11 deadline to keep the government funded. Speaking to Boston business leaders in October, Trahan named a federal artificial intelligence framework, permitting reform and college sports regulation as issues she is watching in the lame-duck session, according to the State House News Service report in The Lowell Sun. She also said she will not seek another term as co-chair of the Democratic Policy and Communications Committee, saying she would rather focus on policy.
