Mejia's margin is significantly larger than the 9 percentage points by which Kamala Harris won the district in the 2024 presidential election. The 11th District was long a Republican stronghold but has become increasingly Democratic since Trump's first term. Not long ago, it was a Republican who won election after election in the district, with Rodney Frelinghuysen holding the seat for 24 years before stepping down voluntarily ahead of the 2018 election. Sherrill first won the seat in 2018's midterm elections, when Democrats flipped dozens of seats to take control of Congress, and in 2024, Sherrill won reelection by about 15 points, while Vice President Kamala Harris, the Democratic presidential nominee, carried the district by nearly 9 points.
The election reduces the gap between parties in the House of Representatives because the seat has been vacant since November, but Republicans still retain their majority with 218 seats to Democrats' 214. Democrats' prospects for the midterm elections have strengthened in recent months, and according to prediction markets Kalshi and Polymarket, Democrats now have an 85% chance of gaining a majority in the House of Representatives. This outcome bolsters the Democratic Party's position in the House, where Republicans currently hold a narrow majority, and contributes to a series of recent successes for Democrats ahead of this year's midterm elections.
Mejia campaigned on a platform of opposition to President Donald Trump, criticizing Trump's pardons of people convicted of Jan. 6-related crimes and faulting him for freezing funds authorized by Congress. She campaigned on populist economic policies and pushing to abolish U.S. Immigration and Customs Enforcement, and she wants to strengthen unions, introduce a national minimum wage of $25 per hour, abolish university fees, and shut down the immigration police ICE. She has accused Israel of genocide in the Gaza Strip and is supported by prominent progressive figures like Bernie Sanders and Alexandra Ocasio-Cortez, and she has criticized the Israeli government and said she stands with Palestinian communities in their pursuit of peace and dignity.
I'm running to bring common-sense leadership to D.C & deliver results for our families, not push a far-left agenda.
Mejia's win ensures Democrats retain the 11th District seat, previously held by Democratic Gov. Mikie Sherrill, and she will serve until January. She emerged from a crowded primary in February and cast the race as a test of Trump's leadership, and as a former leader of the Working Families Alliance and backed by Vermont Senator Bernie Sanders, she represents a significant win for progressives.
Mejia's opponent in the election, Joe Hathaway, is a moderate Republican who has not hesitated to criticize Trump. Hathaway tried to use Mejia's progressive credentials to his advantage, as national Republicans cast her as a socialist.
They could go head to head again in November's election for a full two-year term. The exact voter turnout for the special election has not been confirmed, and details of the prediction markets for other key races beyond the House and Senate majorities remain unspecified, while Mejia's campaign funding compared to Hathaway's is unknown.
