Rep. Jared Moskowitz (D-FL), a Jewish Democrat who is among the most vocal supporters of Israel in Congress, announced on Thursday that he would seek reelection in a new South Florida House district recently drawn to favor Republicans, after his own was largely erased, setting the stage for what is expected to be a costly and competitive race.

“The American people are struggling to afford a regular way of life. Many barely have enough money for their bills and feel squeezed by rising costs,” Moskowitz said in a statement. “We must work together to bring back the American dream for the middle class in America. I have never hesitated to work with anyone across the aisle if I think it’ll improve the lives of my constituents.”

The two-term congressman won’t be unfamiliar to voters in the new 25th Congressional District, the product of recent Republican-led redistricting that dismantled his current seat. The recently approved House map overlaps in many ways with his previous constituency, stretching along Florida’s coast from Delray Beach down south to Miami Beach. The Cook Political Report rates the race a toss-up, even as the district leans Republican.

Moskowitz’s campaign said the district is estimated to be 25% Jewish, a demographic that makes him a strong fit for the seat, according to election analysts.

“Political extremism is expanding, and antisemitism is spreading and becoming mainstream,” he said on Thursday, adding, “When I see people in my own party talking about concentration camps or deporting Jews, I am going to be an immovable object to that movement. My kids are never going to hide in attics,” referring to an antisemitic activist who had sought the Democratic nomination to a congressional seat in Texas.

Moskowitz is facing a left-wing primary challenge from Oliver Larkin, who had also been running in the congressman’s old 23rd Congressional District. The GOP primary for the 25th District is more crowded, and includes former Boca Raton Mayor Scott Singer, former state Rep. George Moraitis and Joe Kaufman, who previously ran against Moskowitz in 2024. Moskowitz reported nearly $1.22 million on hand at the close of the most recent quarter, which ended in March.

Maureen O’Toole, a spokesperson for the National Republican Congressional Committee, said in a statement that Moskowitz had “just sealed his own political fate,” claiming that “by choosing to run in a district President Trump won by nine points, he has guaranteed a loss in November.”

Rep. Debbie Wasserman Schultz (D-FL), a fellow Jewish Democrat whose South Florida seat was also eliminated, announced last week that she would run in the state’s 20th Congressional District, a safe Democratic seat that has been represented by a Black lawmaker for more than three decades.
