A progressive Democrat is headed to Congress.

Analilia Mejia won a special election in New Jersey's 11th Congressional District on Thursday, April 16, beating moderate Republican Joe Hathaway 59.5% to 40%, respectively, according to the Associated Press and CNN. The special election was called to fill a House seat opened by Democrat Mikie Sherrill, now the New Jersey governor, who resigned in November 2025 to run in the gubernatorial election.

Mejia will head to Congress right away, adding a progressive voice to the U.S. House of Representatives at a time the GOP manages a narrow majority in the chamber. Her victory in the Democratic stronghold isn't shocking, but it does signal a progressive ticket can be winning, according to Amy Funck, postdoctoral fellow in philosophy, politics and economics at the University of Pennsylvania.

"Progressives have demonstrated effectiveness in mobilizing primary voters," Funck says.

However, the party attempting to curb President Donald Trump's power in 2026 elections will need to work to tune its message going forward, she says.
