Rep. Byron Donalds entered Florida’s Tuesday primary as the favored candidate in a potentially history-making Republican race to succeed Gov. Ron DeSantis. The ballot also includes contests for the U.S. House and Senate, making the election an early gauge of President Trump’s sway in his adopted home state and of how Republicans’ mid-decade redistricting may reshape congressional competition. Democrats, meanwhile, are trying to make Florida more competitive as population shifts across the Sunbelt raise the stakes for turnout and regional performance.
