Why These Counties Stay Blue
The six counties fall into three patterns.
Large, Diverse Metro Counties
Broward is the most reliably Democratic county left in Florida. Its lean is driven in large part by its substantial Black population, including Caribbean immigrant and Haitian American communities that settled in the county over decades.3Miami Herald. Broward County’s Blue Status Registered Democrats outnumber Republicans by nearly two to one, with more than 464,000 Democrats on the rolls as of early 2026.4Florida Department of State. Voter Registration by County and Party
Orange County, anchored by Orlando, gave Harris a 13.5-point margin.5Orange County Supervisor of Elections. 2024 General Election Summary Like much of the I-4 corridor, the county has a large, diverse population that has trended Democratic even as surrounding suburban and rural areas moved sharply right.
Palm Beach is the shakiest member of the group. Trump actually led in early voting and Election Day ballots there; Harris’s narrow win came entirely from mail-in votes, which she carried roughly two to one. Political scientists have attributed the shift to an ongoing influx of retirees and northern transplants who skew older, whiter, and more Republican.6Palm Beach Post. Trump Nearly Won Palm Beach County
University and Government Centers
Leon County contains Tallahassee, Florida State University, and Florida A&M University, and its politics reflect that concentration of state workers, students, and faculty. Alachua County, home to the University of Florida, fits the same mold. Both retain large Democratic registration advantages: Leon’s Democrats outnumber Republicans 87,632 to 54,639, and Alachua’s 73,186 to 48,084 as of February 2026.4Florida Department of State.

The One Rural County: Gadsden
Gadsden, a small county in the Panhandle just west of Tallahassee, is Florida’s only county where Black residents make up a majority of the population.7News From the States. Gadsden County Democrats Call for Unity That demographic reality has kept it Democratic even as the rest of the Panhandle has become some of the most Republican territory in the country. Democrats outnumber Republicans there by roughly three to one in voter registration.4Florida Department of State. Voter Registration by County and Party
How Much the Blue Margins Have Narrowed
Every one of the six counties produced a thinner Democratic margin in 2024 than it did in 2020:2NBC Miami. How Florida Went More Red
- Broward dropped from 64.6% for Biden to 58.0% for Harris.
- Palm Beach went from a roughly 100,000-vote Biden margin to approximately 5,500 for Harris.
- Orange fell from Biden’s share to 56.1%.
- Leon dropped from 63.5% to 60.3%.
- Alachua dropped from 62.9% to 59.7%.

Statewide, Trump expanded his Florida margin from 3.3 points in 2020 to about 13 points in 2024.2NBC Miami. How Florida Went More Red The uniform decline across the remaining blue counties suggests a systemic shift rather than anything specific to one place.
The Six Counties That Flipped to Trump
Half of Biden’s twelve 2020 counties voted for Trump in 2024: Miami-Dade, Hillsborough, Pinellas, Duval, Seminole, and Osceola.8Florida Phoenix. Osceola County Biggest Flip From Blue to Red
Miami-Dade was the most symbolically significant. The county had not voted for a Republican presidential candidate since George H.W. Bush in 1988. Clinton won it by 29 points in 2016, Biden by seven in 2020, and Trump carried it by 11 points in 2024.9Florida Phoenix.

Osceola County, which is 56% Hispanic with a large Puerto Rican population, posted the biggest swing of the flipped counties. Biden had won it by 14 points in 2020 and Clinton by 25 in 2016, but Trump carried it in 2024 even though Democrats still held a registration lead of more than 20,000 voters there.8Florida Phoenix. Osceola County Biggest Flip From Blue to Red Duval, containing Jacksonville, swung back to Trump by 1.5 points after Biden had flipped it by 3.8 in 2020.2NBC Miami. How Florida Went More Red Hillsborough (Tampa), Pinellas (St. Petersburg), and suburban Orlando’s Seminole County rounded out the flipped group.
Where Democratic Voter Registration Still Leads
Voter registration gives a slightly different picture than election results. As of February 2026, eight Florida counties had more registered Democrats than Republicans: Alachua, Broward, Duval, Gadsden, Leon, Orange, Osceola, and Palm Beach.4Florida Department of State. Voter Registration by County and Party Two of those, Duval and Osceola, voted for Trump in 2024, so registration numbers no longer reliably predict outcomes.
The margins among the remaining Democratic-registration counties vary widely. Broward’s lead of nearly 197,000 voters looks secure for the foreseeable future. Palm Beach’s edge is about 13,000, Osceola’s roughly 12,000, and Duval’s fewer than 5,000.4Florida Department of State. Voter Registration by County and Party As of September 2025, Democratic registration leads in Palm Beach were reported as “barely over 2%” and in Duval 2.5%.11Florida Phoenix.

The statewide picture puts those local figures in context. In 2018, Florida Democrats held a registration advantage of about 257,000 voters. By February 2026, Republicans led by nearly 1.49 million, a total swing of more than 1.7 million.12Florida Department of State.

An analysis of Florida’s swing counties found that the number decided by five points or fewer dropped from roughly 19 or 20 in the 1990s to single digits by the 2000s and has continued falling.15MCI Maps. The Disappearing Swing Counties of Florida Democratic strength now concentrates in a small group of large, diverse urban counties, a handful of university towns, and one majority-Black rural county, while Republicans run up large margins almost everywhere else.
