Most Democrats Don’t Want to Talk About Transgender Athletes. He’s Leaning In.

Senator Ed Markey of Massachusetts might be the only high-profile Democrat in America eagerly campaigning as a supporter of transgender rights.

Even as many other top Democrats have grown cagey on the issue, Mr. Markey is offering a passionate defense of transgender athletes as he runs in a primary contest on Tuesday against Representative Seth Moulton, a more moderate challenger.

Mr. Markey has argued in particular that Mr. Moulton “threw trans kids under the bus” when, shortly after the 2024 election, the congressman attributed Democrats’ defeat in part to their position on transgender issues. Mr. Moulton long defended his remarks but expressed some contrition for them this month.
