Ed Markey and Seth Moulton face off in Massachusetts Senate primary

Key Points:

• Massachusetts holds primary elections featuring a key Senate race where progressive incumbent Sen. Ed Markey faces moderate challenger Rep. Seth Moulton, with Markey backed by prominent progressives and Moulton emphasizing generational change.
• Markey promotes a left-wing agenda including the Green New Deal and Medicare for All, while Moulton, a Marine veteran, campaigns on the need for younger leadership and has received endorsements from moderate figures and the Boston Globe.
• The Democratic primary for Massachusetts' 6th Congressional District to replace Moulton features six candidates, including Dan Koh, endorsed by President Biden and Kamala Harris, with the winner expected to face a Republican opponent in the general election.
• Several incumbent Democrats, including House Minority Whip Katherine Clark, face primary challenges from the left, reflecting ongoing intra-party debates over age and ideological direction.
• Massachusetts Republicans will select a gubernatorial nominee to challenge Democratic Gov. Maura Healey, while voters will also decide on a ballot initiative to replace the state's current primary system with a nonpartisan top-two primary format.
