DEDHAM, Mass. — With just 29 days until the Massachusetts primary election, voters are getting a chance to hear directly from the two Democrats competing for the party’s U.S. Senate nomination.
Incumbent Sen. Ed Markey is seeking a third full term in the Senate. The 80-year-old Democrat faces a challenge from U.S. Rep. Seth Moulton, who has represented Massachusetts’ 6th Congressional District in the House of Representatives for the past 12 years.
The winner of the Democratic primary will advance to the general election in November, where Republican John Deaton awaits.
