Voter Registration Updates for Key Florida Counties – May 15th, 2026
Bottom Line: In a matter of four years, Florida went from being viewed as the ultimate swing state to a red state. The state’s latest voter registration information reflected the continued surge in Republican momentum in Florida that has extended beyond November’s election. The Republican advantage over Democrats stood at a record of 1,505,374 voters last month.
The record performance for Republicans over the prior two election cycles wouldn’t have been possible if not for the rightward turn of three of the four largest counties - Hillsborough, Miami-Dade and Palm Beach. 2024’s election cycle featured President Trump winning traditional blue counties Duval, Hillsborough, Miami-Dade and Osceola – while only losing Palm Beach County by less than one point.
Here's a look at other key counties with net partisan changes over the prior month:
Florida’s remaining blue counties:
- Alachua: Democrats currently lead Republicans by 24,849
- Broward: Democrats currently lead Republicans by 276,841 (GOP +475 net voters)
- Duval: Democrats currently lead Republicans by 5,022 (GOP +40 voters)
- Gadsden: Democrats currently lead Republicans by 11,398
- Leon: Democrats currently lead Republicans by 32,662
- Orange: Democrats currently lead Republicans by 88,078
- Osceola: Democrats currently lead Republicans by 11,833 (DEM +17 voters)
- Palm Beach: Democrats currently lead Republicans by 9,976 (GOP +1,422 voters)
At the peak of the Democrat voter registration advantage in Palm Beach County, Democrats held an advantage of 138,400 voters. Democrats now hold the smallest advantage in the county’s history below 10 thousand voters. Here are other counties of interest locally and across the state:
- Hillsborough: Republicans flipped the county to a GOP majority last year with a lead of 22,632 (GOP +927 net voters)
- Indian River: Republicans currently hold an advantage of 36,104 (GOP +32 voters)
- Martin: Republicans now hold an advantage of 39,177 (GOP +107 voters)
- Miami Dade: Republicans flipped the county to a GOP in May with the Republican advantage now standing at 46,599 (GOP +2,758 voters)
- St Lucie: Republicans lead Democrats by 14,736 (DEM +144 voters)
The biggest storyline in Florida’s political scene continues to be the state’s blue counties becoming far less blue. Palm Beach County represents one of the most significant shifts in the state. Early in this midterm election year, changes in voter registrations will be the most visible sign of political trends within the state.
