Incumbent Ed Markey and Seth Moulton are running in the Democratic primary for U.S. Senate in Massachusetts on September 1, 2026.
This is one of several primaries this year in which age has become an issue. Markey is 80, and Moulton is 47. Markey is running on his record, while Moulton has said he would be part of a new generation of leadership.
Markey said, "I'm more energized than I've ever been before. I am crisscrossing the state. I am fighting for families. It brings out the Malden in me every single day, seeing what Trump is doing to families. Congressman Moulton has a hard time keeping up with me in the course of this campaign. So for me, if somebody can't do the job, they should just step down. But I can do the job."
