Who is my U.S. representative in MA-06?
Your current U.S. Representative for MA-06 is Seth Moulton (D), who's represented the district (the North Shore, from Lynn to the New Hampshire border, stretching west to the Merrimack Valley) since January 2015. House Worth noting: Moulton is not seeking re-election to this seat — he's running for U.S. Senate against incumbent Ed Markey instead. So MA-06 is an open race this cycle, with several Democratic and Republican candidates running. The primary is September 1, 2026, and the general election is November 3, 2026. WBUR News If you're specifically in Lexington, it's worth double-checking your exact congressional district, since Lexington sits near district boundaries in Massachusetts (it could be in MA-05 rather than MA-06 depending on your precise address). Want me to help confirm which district you're actually in?
