Republicans built a legislative supermajority through elections before two House Democrats switched parties and the Senate Democratic leader became unaffiliated. Now Democrats are trying to rebuild amid a GOP voter-registration advantage exceeding 1.54 million — and signs that some Republican-held districts remain competitive.

By Florida National News

TALLAHASSEE, Fla. (FNN) — Six years ago, Florida Democrats held enough seats in the state House to prevent Republicans from reaching a two-thirds supermajority.

Today, the political landscape looks dramatically different.

Republicans emerged from the 2020 election with 78 of the Florida House’s 120 seats, two short of the 80 required for a two-thirds majority. Democrats held 42.

By the end of the 2024 election, Republicans had 85 seats and Democrats 35. Then two newly reelected Democratic representatives — Susan Valdés of Tampa and Hillary Cassel of Broward County — switched to the Republican Party, expanding the GOP advantage to 87-33.

Four months later, another high-profile departure came in the Senate. Democratic Leader Jason Pizzo left his party and became unaffiliated.

Those defections attracted significant attention, but they can obscure the larger story of Florida’s political transformation.

Party switching did not create Republican control of Tallahassee. Elections did.

The subsequent defections widened an advantage Republicans had already established at the ballot box.

Now, with the Nov. 3, 2026, general election approaching, Democrats face a more complicated test than simply winning several competitive races. They are attempting to rebuild legislative representation while confronting a Republican voter-registration advantage of more than 1.54 million active voters.

At the same time, Democratic victories in several 2026 legislative contests suggest the statewide numbers do not necessarily determine what happens district by district.

That creates three questions heading into November: Can Democrats win back legislative seats? Can Republicans protect the districts underlying their supermajority? And can both parties retain the lawmakers voters elect under their banners?

From 42 House Democrats to Republican Supermajority

The clearest starting point is 2020.

Republicans won 78 House seats, compared with 42 for Democrats. With 80 seats needed for a two-thirds majority, Democrats retained enough representation to keep Republicans below that threshold.

Former Democratic Reps. Daisy Morales of Orange County and James Bush III of Miami-Dade County were among the lawmakers elected as part of that 42-member Democratic delegation.

The balance changed decisively two years later.

Republicans expanded their House majority to 85 seats in the 2022 election, crossing the two-thirds threshold. The 2024 election again produced an 85-35 Republican advantage.

That chronology is important because it separates two different political developments.

Republicans gained the supermajority through elections. The Democratic defections came afterward.

The distinction also provides a clearer measurement of Democratic decline: from 42 House seats after the 2020 election to 35 after the 2024 election — a net reduction of seven seats before either Valdés or Cassel changed parties.

Two House Democrats Switch Parties

The first post-election departure came quickly.

On Dec. 9, 2024, Valdés announced she was leaving the Democratic Party and joining the Republican Party, just weeks after voters reelected her as a Democrat.

Her switch moved the House from 85 Republicans and 35 Democrats to 86-34.

Less than three weeks later, Cassel followed.

On Dec. 27, Cassel announced she also was leaving the Democratic Party for the GOP.

The House moved to 87 Republicans and 33 Democrats.

Florida Democratic Party Chair Nikki Fried criticized Cassel’s decision at the time while acknowledging the difficult political environment facing Democrats.

The significance went beyond losing two caucus members.

A direct switch from Democrat to Republican changes the partisan margin by two: Democrats lose one seat while Republicans simultaneously gain one.

The two defections therefore transformed an 85-35 House into an 87-33 chamber without another general election being held.

Senate Democratic Leader Becomes Unaffiliated

The next departure was politically significant but fundamentally different.

On April 24, 2025, Pizzo announced he was leaving the Democratic Party while serving as Senate Democratic leader. His voter registration became No Party Affiliation the following day.

He did not become a Republican.

That distinction matters when measuring party switching. Valdés and Cassel directly increased the Republican House caucus. Pizzo’s departure did not add a Republican senator.

It nevertheless cost Democrats a sitting senator and their caucus leader. Sen. Lori Berman subsequently became Senate Democratic leader.

An FNN review of these high-profile departures from 2020 through 2026 therefore identifies three sitting Democratic state lawmakers leaving the party:

Valdés: Democrat → Republican

Cassel: Democrat → Republican

Pizzo: Democrat → No Party Affiliation

FNN’s review did not identify a comparable sitting Republican Florida legislator who switched directly to the Democratic Party during the same period.

But the numbers reinforce the larger point: the movement of individual lawmakers accelerated a political shift that had already occurred through elections.

The Bigger Transformation Is Outside the Capitol

The change in Florida’s voter-registration balance has been even more dramatic than the movement inside the Legislature.

In 2020, Florida reported 5,315,954 active registered Democrats and 5,218,739 Republicans.

Democrats held an advantage of 97,215 voters.

As of July 31, 2026, Florida reported:

Republicans now lead Democrats by 1,541,333 active registered voters, according to the Florida Division of Elections.

Measured from the Democratic advantage in 2020 to the Republican advantage in July 2026, the Republican-Democratic registration margin shifted by approximately 1.64 million voters.

That is one of the most important numbers for understanding Florida politics entering the 2026 general election.

But it also requires careful interpretation.

A decline in active Democratic registration cannot automatically be described as more than a million Democrats becoming Republicans.

Voter rolls change for multiple reasons, including deaths, people moving into or out of Florida, new registrations, inactive classifications, list maintenance and voters changing party affiliation.

The more defensible conclusion is narrower but still consequential:

Florida moved from a slight Democratic registration advantage in 2020 to a Republican advantage exceeding 1.5 million active voters by mid-2026.

That is a structural change extending far beyond a handful of lawmakers changing parties.

More Than 3.3 Million Voters Belong to Neither Major Party

There is another number that complicates any attempt to translate registration totals directly into election outcomes.

Florida had more than 3.32 million active voters registered with no party affiliation as of July 31.

That electorate is larger than the population of many states.

Those voters do not form a single ideological bloc, and their existence does not erase the GOP registration advantage. But they reinforce why statewide party registration alone cannot determine the outcome of individual legislative races.

Florida legislative elections are decided district by district.

Candidate quality, fundraising, turnout, district boundaries, local demographics, campaign organization and voter enthusiasm can produce outcomes that differ from statewide trends.

That distinction has become especially relevant in 2026.

Democrats Have Shown They Can Still Flip Republican-Held Seats

For Democrats, the strongest counterargument to the state’s broader Republican trend has come from actual election results.

Democrat Emily Gregory flipped House District 87 in a March 2026 special election, defeating Republican Jon Maples.

The result drew attention because Republican Mike Caruso had carried the district by roughly 19 percentage points in 2024.

Democrat Brian Nathan also flipped Senate District 14, defeating Republican Josie Tomkow by just over 400 votes.

Those results demonstrated that at least some Republican-held legislative districts remain competitive under the right electoral conditions.

Florida Democrats have also expanded year-round organizing and made breaking the Republican legislative supermajority a central objective of the 2026 cycle.

But special elections come with an important warning.

They typically involve smaller and sometimes substantially different electorates than November general elections.

Republicans have pointed to House District 35 as evidence of that difference. Democrat Tom Keen won the Orlando-area seat in a January 2024 special election, only for Republicans to reclaim it during the November general election.

The 2026 Democratic flips therefore provide evidence of competitiveness, not proof of a statewide reversal.

November will provide the larger test.

Republicans Have a Structural Advantage — But Still Must Defend It

The challenge facing Republicans is different.

They do not need to rebuild a legislative majority. They already possess one.

They enter the election with a House supermajority and a statewide registration advantage that would have been difficult to envision when Democrats still led voter registration in 2020.

The question is whether those structural advantages continue translating into legislative victories across Florida.

A statewide registration lead does not make every Republican-held district equally secure.

The Gregory and Nathan victories demonstrate that Democrats can still win Republican-held territory, particularly when turnout, candidate performance and district conditions align.

For Republicans, November therefore becomes a test of durability.

Can the party maintain the legislative gains it accumulated over multiple election cycles while defending districts Democrats now view as opportunities?

The Democratic Challenge Is Now Twofold: Win Seats and Keep Them

For Democrats, the experience following the 2024 election introduces another issue that cannot be measured solely on election night.

Political parties invest substantial resources recruiting candidates, raising money, organizing voters and winning legislative seats.

But caucus strength ultimately depends on keeping those lawmakers after they take office.

The Valdés and Cassel switches demonstrated how quickly that calculation can change.

Democrats won 35 House seats in November 2024. Weeks later, they had 33 members because two lawmakers elected as Democrats joined Republicans.

Pizzo’s departure presented a different version of the same organizational problem: Democrats lost their Senate leader even though he did not join the Republican Party.

That creates two separate measurements for Democratic rebuilding:

Electoral growth: Can Democrats increase the number of legislative seats they win?

Caucus stability: Can they retain the lawmakers elected as Democrats?

Winning without retention can limit rebuilding. Retention without winning additional districts leaves the party’s minority position largely unchanged.

Democrats need both if their objective is to reduce Republican legislative dominance.

Former Lawmakers Add Another Dimension to the Rebuilding Debate

The 2026 cycle also raises questions about how a minority party decides where to invest limited political resources.

Morales and Bush were members of the 42-seat Democratic House delegation elected in 2020. Both later left the Legislature and subsequently sought returns through Democratic primaries.

Their races, districts and political circumstances are different and should be evaluated separately.

But their candidacies illustrate a broader strategic issue facing any party attempting to rebuild:

How should resources be divided among defending incumbents, supporting challengers in opposition-held districts, recruiting newcomers and considering former lawmakers seeking a return to office?

There is no single formula.

A former legislator may bring name recognition, fundraising relationships and legislative experience. A newcomer may offer stronger district appeal or represent a changing electorate. An incumbent may require significant resources simply to prevent the party from losing another seat.

The effectiveness of those decisions ultimately can be measured by outcomes.

Does the party gain seats?

Does it protect vulnerable seats?

Does it expand into territory previously controlled by the opposition?

And does it retain the lawmakers it helped elect?

Those questions become particularly important when one party is operating from a substantial numerical disadvantage.

What Has Actually Changed Since 2024?

For Democrats, there are identifiable changes since the immediate aftermath of the 2024 election.

The Florida Democratic Party retained Nikki Fried as chair in 2025, expanded its year-round organizing operation and increased regional staffing ahead of the 2026 cycle.

The party has continued its Take Back Local initiative aimed at municipal and local races while placing greater emphasis on legislative contests.

And Democrats have produced tangible 2026 victories, including Republican-held legislative seats.

Those developments provide evidence of organizational activity and some electoral progress.

They have not, however, erased the larger structural imbalance.

Republicans still hold the legislative supermajority.

Republicans still lead statewide active voter registration by more than 1.54 million.

Democrats still must gain substantially more legislative ground before control of either chamber becomes competitive.

The most accurate description of the Democratic position heading toward November is therefore neither collapse nor comeback.

It is a rebuilding test whose results remain unresolved.

Why It Matters to Florida Voters

The significance extends beyond the internal fortunes of either political party.

A legislative supermajority can affect the balance of power in Tallahassee because it gives the majority party sufficient numbers to take actions that require more than a simple majority.

The size of the minority caucus also affects committee representation, legislative negotiations, the ability to sustain or challenge certain procedural actions and the overall political leverage available to the opposition.

That makes legislative competition relevant even when control of a chamber is not immediately in doubt.

For Democratic voters, 2026 provides a measurable test of whether the party can translate organizing and special-election victories into broader legislative gains.

For Republican voters, it tests whether the political coalition that produced the GOP’s current advantage remains durable in a general election.

For NPA and minor-party voters, it underscores the potential importance of voters outside either major party in competitive districts.

And for Florida voters generally, it provides a way to distinguish political narratives from measurable results.

The Numbers to Watch on Nov. 3

The 2026 general election is scheduled for Nov. 3. Florida’s voter-registration deadline is Oct. 5, with mandatory statewide early voting scheduled for Oct. 24-31.

Rather than judging Florida’s political direction from one race, three measurements will provide a clearer picture.

First: Legislative seats.
Do Democrats finish the election with more House and Senate seats than they entered with, or do Republicans maintain or expand their advantage?

Second: Republican registration advantage versus district results.
Does the GOP’s statewide registration lead translate consistently into legislative victories, or do Democrats continue outperforming the statewide environment in selected districts?

Third: Caucus stability.
After voters choose their lawmakers, do the members remain with the parties under whose banners they were elected?

Together, those measurements will provide a better indication of Florida’s direction than any isolated special election, party switch or registration statistic.

A Six-Year Transformation

The numbers tell the story clearly.

In 2020, Democrats held 42 Florida House seats, and Republicans were two seats short of a supermajority.

Democrats also held a 97,215-voter statewide registration advantage.

By 2024, Republicans had won 85 House seats, already exceeding the supermajority threshold.

Two Democratic defections subsequently increased the Republican House caucus to 87 while reducing Democrats to 33.

And by July 2026, Republicans held a statewide registration advantage of 1,541,333 active voters.

Those developments represent a profound shift in Florida politics.

But elections are snapshots, not permanent guarantees.

Democrats’ 2026 legislative flips show that Republican-held districts can still change hands. Republicans’ statewide numbers show the scale of the challenge Democrats face in turning isolated victories into sustained gains.

That is why Nov. 3 matters.

The central question is no longer simply whether Florida has moved toward Republicans. The electoral and registration numbers already establish that Republicans have gained substantial ground since 2020.

The unanswered question is whether that movement has reached a durable plateau — or whether Democrats have begun rebuilding enough support to reverse some of those losses.

The first meaningful statewide answer comes in November.

NEXT FNN ANALYSIS: Where Is the Money Going?

Election results are only one measure of rebuilding. Political investment is another.

FNN’s next examination should follow the money behind Florida House races: where Democratic political organizations are spending, which candidates receive institutional support, how much is directed toward Democratic primaries and how those expenditures compare with resources devoted to defending Democratic seats or challenging Republican-held districts.

That examination can include the Florida House Democratic Campaign Committee, campaign committees and related political spending while carefully distinguishing verified campaign-finance transactions from allegations or disputed claims involving individual campaigns.

The central question is measurable:

At a time when Democrats say they are trying to break the Republican supermajority, are Democratic political resources being deployed in ways that expand, protect or reduce the party’s representation in the Florida House?

That is a separate story — and one best answered through campaign-finance records rather than political rhetoric.
