Vindman and Nixon Close In on a Senate Primary With Moody Leading in Polls

Florida Democrats will choose between Alex Vindman and state Representative Angie Nixon on August 18 in a closed primary that will decide who challenges appointed U.S. Senator Ashley Moody in this year's special election. Recent public polling shows Moody leading both potential opponents, and the two Democrats have spent the closing weeks of the primary making different arguments about how a Democrat wins statewide in Florida.

The seat became vacant when Marco Rubio resigned to serve as Secretary of State in President Donald Trump's second administration. Governor Ron DeSantis appointed Moody, then Florida's attorney general, to fill the vacancy in January 2025. Under Florida's process, the appointment runs until a special election, which is being held alongside the regular general election on November 3.

Moody faces her own primary. Florida Republicans will choose among the incumbent and challengers Chris Gleason, Neelam Taneja Perry and Ernest Rivera on August 18. Moody enters that contest with the advantages of incumbency, statewide name recognition from two terms as attorney general and the backing of the state party apparatus.

Where the polling stands

A University of North Florida public opinion poll released this month showed Moody with an eight-point lead over Nixon and a 10-point lead over Vindman. The finding that Nixon runs slightly closer than Vindman complicates the conventional read of the race, since Vindman has drawn considerably more national attention and fundraising.

Public polling this far from a general election measures name recognition and partisan baseline more than it predicts outcomes, and Florida has repeatedly produced polling misses in both directions over the past decade. The state's registration advantage has shifted toward Republicans over that period, which is the structural fact underlying Moody's lead in these surveys.

Both Democratic campaigns have used the polling to argue their own case. Vindman's campaign has pointed to a national environment it describes as unfavorable to Trump and argued that provides a path against an appointed senator who has not previously faced Florida voters in a federal race. Nixon's supporters point to her closer showing as evidence that a candidate with deep Florida roots travels better in the state.

The Vindman argument

Vindman's campaign has identified a path to victory built around turning out voters registered without party affiliation, the fastest-growing bloc in Florida registration. His team has described Moody as untested in a competitive statewide federal race and has emphasized national fundraising, an area where he has been competitive.

The independent voter strategy reflects a real change in the Florida electorate. Voters registered with no party affiliation now make up a substantial share of the state's rolls, and they cannot participate in Florida's closed primaries. That makes them irrelevant to the August contest and central to November, a sequencing problem for any candidate whose general election theory depends on them.

Vindman came to national prominence as a witness in the first impeachment inquiry into Trump during the previous administration, a background that gives him a fundraising base and a defined national profile. Whether that profile helps or hurts in Florida is one of the questions the primary will answer.

The Nixon argument

Nixon is a sitting state representative from Jacksonville with a record in the Florida House and long-standing ties to Duval County political organizations. Her case rests on the argument that a Democrat who wins statewide in Florida will do it by consolidating and turning out the party's existing base, particularly Black voters in Jacksonville, Orlando, Tampa and South Florida, rather than by persuading independents.

That theory has historical support in Florida. Democratic statewide performance has tracked closely with turnout in the state's urban cores, and Democratic underperformance in recent cycles has coincided with turnout drops in those same areas rather than with dramatic swings among independents.

Nixon's slightly stronger showing against Moody in the UNF poll gives that argument empirical footing, though the difference falls within the range where a single survey cannot settle the question. Her challenge is resources: Vindman's national fundraising has given him an advertising advantage in a state with ten media markets, one of the most expensive campaign environments in the country.

Moody's position

Moody has served in the Senate since January 2025 after eight years as Florida's attorney general. She has the institutional advantages that come with incumbency, including committee assignments and the ability to generate news through official activity, and she is running in a state where Republicans hold a registration advantage.

Her primary challengers have not demonstrated significant fundraising or polling support, and the contest is widely expected to produce a comfortable win. That lets her campaign focus resources on the general election while the Democratic primary consumes its candidates' money and attention through August.

The appointed-incumbent dynamic cuts both ways. Moody has never appeared on a Florida ballot for this office, which Democrats have made a talking point, but she has won statewide twice for attorney general, which undercuts the argument that she is unknown to Florida voters.

What is at stake for Florida

Florida's two Senate seats carry weight on issues that dominate the state's agenda: federal disaster funding after hurricanes, National Flood Insurance Program reauthorization, immigration policy affecting a state with large immigrant communities, agricultural labor rules central to Florida farming, and appropriations for the space program at Cape Canaveral and Kennedy Space Center.

The senator elected in November will serve out the remainder of the term associated with the seat and will vote on federal judicial nominations, including judges for the federal district courts in Florida and the Eleventh Circuit Court of Appeals, which hears appeals from Florida, Georgia and Alabama.

Control of the Senate more broadly is contested in this cycle, which is why national money has flowed into a race that Florida's recent partisan lean would otherwise mark as safe. That national interest is likely to intensify after the primaries settle the matchup.

Florida's closed primary system

Florida conducts closed primaries, meaning only voters registered with a political party may vote in that party's primary contest. Voters registered with no party affiliation are excluded from partisan primaries entirely, a rule that has become more consequential as the share of unaffiliated registrations has grown.

The registration deadline for the August 18 primary has already passed under Florida's 29-day rule, meaning the electorate for both contests is now fixed. Voters who wanted to change parties to participate in a particular primary needed to do so well before the campaigns reached their closing arguments.

There is one significant exception. Florida's universal primary contest provision opens a primary to all voters when every candidate for an office is from the same party and the winner will face no opposition in the general election. That provision does not apply here, since both parties have contested primaries and a general election follows.

How a special Senate election works in Florida

When a United States Senate seat becomes vacant in Florida, the governor appoints a replacement who serves until a special election fills the remainder of the term. That is the process that placed Moody in the seat following Rubio's resignation to become Secretary of State.

The special election is being conducted concurrently with the regular November 3 general election, which consolidates administration and dramatically increases turnout compared to a standalone special election. Concurrent scheduling also means the Senate contest shares the ballot with the governor's race, cabinet offices and legislative contests, so voters encounter it in the context of a full ballot rather than as a single question.

The winner serves the remainder of the term attached to the seat rather than a fresh six-year term. That distinction matters for the next cycle, since the seat will come up again on its regular schedule.

The money and the map

Florida is among the most expensive states in the country to campaign in, with ten separate media markets stretching from Pensacola to Key West. Reaching the full state through broadcast advertising requires buying in Miami-Fort Lauderdale, Tampa-St. Petersburg, Orlando, Jacksonville, West Palm Beach, Fort Myers-Naples, Panama City, Tallahassee, Gainesville and Pensacola.

That cost structure rewards candidates with national fundraising networks and penalizes those relying primarily on in-state donors, which is the structural advantage Vindman brings to the Democratic primary. Nixon's counterargument is that paid media matters less than organizing in a low-turnout August primary where the electorate is small and identifiable.

Campaign finance reports filed with the Federal Election Commission provide the public record of both campaigns' resources. Those filings, along with independent expenditure reports from outside groups, will show in the closing weeks whether national money treats the Florida seat as genuinely competitive or as a lower priority than races in other states.

What the general election would turn on

Florida's statewide races over the past several cycles have been decided by a combination of registration advantage, turnout differential and margins among voters registered without party affiliation. Republicans have built a registration lead that Democrats did not face in earlier cycles.

Overcoming that requires either exceptional turnout among Democratic-leaning constituencies or a meaningful advantage among unaffiliated voters, and recent Democratic statewide campaigns have achieved neither at sufficient scale. Whichever nominee emerges faces that structural problem regardless of their individual strengths.

Issue environment is the variable both campaigns hope to shape. Property insurance costs, housing affordability and utility bills are pocketbook concerns that cut across partisan lines in Florida, and Democratic campaigns have increasingly organized around them rather than around national issues.

Moody's campaign will emphasize her record as attorney general and her Senate service, and will benefit from running alongside a Republican gubernatorial nominee in a state where straight-ticket voting patterns are strong. Ballot position and the top of the ticket matter more in Florida than campaign-specific factors in most cycles.

What's next

Early voting opens in most Florida counties in early August, and vote-by-mail ballots are already circulating. Florida's closed primary system means only voters registered with a party may participate in that party's contest, a rule that excludes the state's large no-party-affiliation bloc from the August 18 decision.

The general election is November 3. Between the primary and that date, the nominees will campaign across Florida's ten media markets, and the Senate contest will share the ballot with the governor's race, cabinet offices, congressional seats and legislative races.

The Florida Press will cover the August 18 results in both primaries and will continue tracking polling, fundraising and campaign activity through the general election.
