New Jersey special election results. See latest numbers from Mejia's win

A progressive Democrat is headed to Congress.

Analilia Mejia won a special election in New Jersey's 11th Congressional District on 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.

"More broadly, Democrats have advantages due to the economy and backlash to actions associated with the Trump administration, but internal divisions remain a vulnerability," she says. "If Democrats want to take the House this fall, they need to first get their own house in order."

What does this mean for Democrats?

The heavily Democratic district wasn't likely to elect a Republican, William Galston, senior fellow in governance studies at the Brookings Institution, previously told USA TODAY. Which Democrat would win in the blue district was the questions.

Mejia emerged as the nominee in the February primary after the American Israel Public Affairs Committee (AIPAC) poured more than $2 million into opposing her chief competitor, moderate Democratic former Rep. Tom Malinowski. Mejia's campaign led the race in fundraising and was endorsed by a broad coalition of Democrats, including Massachusetts Sen. Elizabeth Warren and New York Rep. Alexandria Ocasio-Cortez, as well as Independent Vermont Sen. Bernie Sanders.

Mejia earned 77,620 votes while Hathaway had 52,122, according to Associated Press and CNN. A third candidate, Independent Alan Bond, scored 0.5% of the vote, or 595 votes.

Mejia's victory in this special election foreshadows new challenges as factions of Trump's opposing party organize how to counter Republican control of Washington, Funck says.

"This race is more about who lost than who won," Funck says. "Progressives may frame a Mejia victory as evidence of growing national support, but Malinowski’s primary loss appears more tied to strategic missteps."

This race isn't over

Mejia celebrated with supporters at a watch party at Montclair Art Museum on April 16, saying, "It is not radical to say that in the wealthiest nation in the world that we should do more to protect the health of its people."

She later lumped Hathaway with Trump, Elon Musk and Amazon founder Jeff Bezos as the true radicals “who subvert the Constitution” and “act with impunity.”

These candidates could meet again soon. In his election night remarks, Hathaway said he was proud of the campaign he ran, and indicated it won't be his last bid for the U.S. House seat.

"While the result tonight is not what we hoped for, our work is only just beginning," the Republican said.

Mejia will serve the next eight months of Sherrill's term but then must run for a full term. She'll face another primary election in June to be on the fall ballot, which also gives Republicans another opportunity to fight for the seat.

"In June, turnout will likely be higher than usual for New Jersey primaries, driven by economic concerns and dissatisfaction with ongoing conflicts abroad," Funck says. "Anger tends to increase voter engagement."

In the meantime, Mejia will be a full-time member of Congress, representing the 11th District constituents. She told NorthJersey.com, part of the USA TODAY Network, that her first priority will be "to use every tool Congress has to hold this administration accountable and stop the democratic backslide."

She brings a unique combination of political experience and an activist background, Funck says.

"Mejia differs [from other progressives] in that she has held leadership positions across both government and private organizations and brings an established network," she says. "That suggests she is more likely to work within institutional channels rather than position herself in opposition to party leadership. She’ll likely be viewed as an effective, pragmatic, and accessible colleague."
