Voter Registration Updates for Key Florida Counties – March 3rd, 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 1.48 million 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. Last November’s election featured President Trump winning traditional blue counties Duval, Hillsborough, Miami-Dade and Osceola – while only losing Palm Beach County by less than one point.
At the peak of the Democrat voter registration advantage in Palm Beach County, Democrats held an advantage of 138,400 voters. Democrats now hold an advantage of 12,662 voters a total that’s 1,659 fewer voters than the previous update, as the potential path towards Republicans gaining the upper hand in for the first time in the county’s history appears possible as soon as this year’s midterm election year. Here's a look at other key counties with net partisan changes over the prior month:
- Broward: Democrats currently lead Republicans by 278,394 (GOP +1,238 net voters)
- Duval: Democrats currently lead Republicans by 4,719 (DEM +237 voters)
- Hillsborough: Republicans flipped the county to a GOP majority earlier this year with a lead of 21,705 (GOP +2,257 voters)
- Indian River: Republicans currently hold an advantage of 36,065 (GOP +207 voters)
- Martin: Republicans now hold an advantage of 38,968 (GOP +204 voters)
- Miami Dade: Republicans flipped the county to a GOP in May with the Republican advantage now standing at 42,709 (GOP +1,091 voters)
- Osceola: Democrats currently lead Republicans by 11,895 (GOP +226 voters)
- St Lucie: Republicans lead Democrats by 14,736 voters (GOP +156 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.
