Lancaster drops out of 6th Congressional District race, endorses Tram Nguyen – NBC Boston

Meet the five Democratic candidates running to represent Massachusetts’ 6th Congressional District.
Dr. Mariah Lancaster has ended her campaign for Massachusetts’ open 6th Congressional District seat and endorsed fellow Democratic candidate State Rep. Tram Nguyen.
Lancaster, a veterinarian who has also served in roles at the U.S. State Department and the U.S. House of Representatives, announced her decision Saturday in a post on social media.

“Throughout this race, I have had the pleasure of getting to know Tram as a colleague. With every debate, every community event, every speech, I was increasingly impressed with her work ethic, backbone, and integrity. That is exactly why I know she is prepared to be the progressive champion we need. She has the skills and the drive to deliver for working families throughout the district and will champion the needs of our students, our fishermen, our conservationists, and our immigrant communities. She is a union member who understands that labor rights are the backbone of our democracy and the key to the future of the Democratic Party,” Lancaster wrote.
The 6th District seat became open after U.S. Rep. Seth Moulton announced he would challenge Sen. Edward Markey in the Democratic primary ahead of the 2026 midterm elections.
With Lancaster’s withdrawal, there are five Democratic candidates remaining.
“In the final days of this race, the most important thing I can do is help ensure the Sixth District is represented by someone who will fight for our progressive values. That is what I am choosing to do today,” Lancaster posted.
Nguyen has also received endorsements from U.S. Reps. Ayanna Pressley and Lori Trahan.
