Democratic socialist Angie Nixon scored an upset victory on Tuesday in Florida’s Democratic primary race for the U.S. Senate, as media outlets projected she defeated former national security official Alex Vindman.

Nixon, who has served in the Florida state legislature since 2022, will face Republican Senator Ashley Moody in November’s general election.

The winner will finish the remaining two years of former Senator Marco Rubio, who now serves as President Donald Trump’s secretary of state.

Vindman, a retired Army officer, rose to prominence in 2019 when he testified to Congress during President Donald Trump’s first impeachment about a call between Trump and Ukrainian President Volodymyr Zelenskiy.

Florida voters on Tuesday picked candidates to run in the November election, which will determine control of Congress.

In other results, Representative Jared Moskowitz was projected on Tuesday to win the Democratic primary in Florida’s 25th congressional district, fending off challenger Oliver Larkin, who was backed by the Democratic Socialists of America.

Moskowitz was running in a new district after Florida’s redistricting this year, intended to help Republicans gain seats in Congress in the November general election.

In another Florida primary, Mike Beltran, a state representative, was projected to win the Republican nomination in the newly redrawn 14th congressional district. He will face Democratic Representative Kathy Castor. The district is now seen as tilting toward Republicans.
