Rep. Seth Moulton launches Senate bid against Ed Markey in Massachusetts

Rep. Seth Moulton, D-Mass., announced this morning that he is launching a bid for Senate, challenging Sen.

Rep. Seth Moulton, D-Mass., announced this morning that he is launching a bid for Senate, challenging Sen. Ed Markey. Moulton's bid marks the first high-profile challenge to Markey, a Democrat who has served in Congress for nearly five decades.

"Real people across Massachusetts are being hurt by Democratic leaders refusing to do everything they can to win," he said in his announcement video. "We've got to look in the mirror and be honest: It's time for change."

Moulton, 46, invoked age in his argument against Markey, who is 79 years old. The age argument comes as Democrats continue to to grapple with the aftermath of former President Joe Biden's failed campaign, where polling indicated voters widely perceived him to be too old to run for a second term, ultimately prompting renewed conversations about generational change and aging politicians.

"We're in a crisis, and with everything we learned last election, I just don't believe Senator Markey should be running for another six year term at 80 years old," Moulton said in his announcement video. "Even more, I don't think someone who's been in Congress for half a century is the right person to meet this moment and win the future."

"Senator Markey is a good man, but it's time for a new generation of leadership, and that's why I'm running for U.S. Senate," he added.
