Ed Markey Just Won His Primary by Nearly 30 Points. Trans Rights Were the Reason.

Sen. Ed Markey didn’t just win his Democratic primary on September 1 — he won it by nearly 30 points, and he did it after making transgender rights one of the loudest parts of his campaign. In a midterm cycle where plenty of Democrats have quietly tried to change the subject when trans issues come up, Markey did the opposite, and LGBTQ+ advocacy groups are now pointing to Massachusetts as proof that leaning in works.

The 80-year-old senator faced a serious challenge from Rep. Seth Moulton, who framed his campaign around “generational change” and largely avoided direct culture-war fights. That framing ran into trouble in 2024, when Moulton told a reporter he wouldn’t want his daughters “playing sports with someone who has a d***” — a comment about transgender athletes that he later apologized for, saying it “hurt people” in his district. He spent much of the following two years trying to walk it back. Voters didn’t let him.

”Trans rights are human rights”

Markey made the contrast explicit throughout the race. “The demonization of the trans community requires political leaders to stand up and to protect them against the unconscionable attacks,” he said during the campaign. On primary night, his victory speech didn’t hedge: “Trans rights are human rights,” he told supporters — a line that’s become something close to a rallying cry among Democrats trying to figure out how to talk about trans issues without flinching.

Advocates for Trans Equality, a national group, had endorsed Markey specifically because of that posture, and LGBTQ+ organizers in Massachusetts framed the result as a direct rebuke of the idea that Democrats need to soften or sideline trans rights to win swing voters. Moulton’s defeat — by a margin few predicted this early in the cycle — landed as the opposite lesson: that treating trans people as a liability to be managed, rather than a constituency to be defended, can cost you the room.

A test case for a bigger argument

The Markey-Moulton primary landed in the middle of an argument Democrats have been having with themselves since the party’s rough 2024 cycle: whether trans rights are a political liability that costs the party moderate and swing voters, or whether that framing is itself the mistake — a form of pre-emptive surrender that alienates a committed base without actually winning over the voters it’s meant to appease. Moulton was, in effect, a test of the first theory. He ran as the candidate willing to create some distance from what he and his allies characterized as an unpopular position, positioning himself as more electable in a general election even in deep-blue Massachusetts.

Massachusetts voters didn’t just reject that theory — they rejected it emphatically, in a state Moulton represents in Congress and where he might have expected some hometown goodwill to cushion the blow. A near-30-point loss to an 80-year-old incumbent who leaned all the way into the fight isn’t the outcome you’d predict if “soften on trans rights” were actually a winning strategy with primary voters, even relatively moderate ones in a state like Massachusetts.

What happens next

Markey now moves to the general election on November 3 against Republican nominee John Deaton, in a state where Democrats hold a significant structural advantage. He’s heavily favored to win a fifth full term. But the primary result is already being read well beyond Massachusetts. With trans rights facing sustained pressure at the federal level — from military discharge proceedings to Medicaid restrictions on gender-affirming care for minors — Democratic strategists are watching for which candidates follow Markey’s approach and which follow Moulton’s original instinct to hedge.

It’s one data point, from one state, in one primary — nobody should oversell what a single Senate race proves about a national electorate. But for a party still hunting for a coherent message heading into the 2026 midterms, a blowout win for the candidate who refused to hedge is the kind of result that tends to get studied closely by campaign strategists well outside New England.

For a party still arguing internally about how much to talk about trans issues heading into November, Massachusetts just supplied a data point that’s hard to spin: the candidate who stood up loudest for trans people won, and the one who wavered lost by a landslide.
