Florida's 23rd District margin of victory
Short Answer
Both the model and the market expect Democrats to win Florida's 23rd District by 2 or more points. This consensus is supported by a new redistricting map, signed on or around May 6, 2026, which transformed the district to a D+13 lean and significantly increased the likely Democratic margin of victory.
1. Executive Verdict
- The new redistricting map, signed May 6, 2026, created a D+13 lean.
- Kamala Harris secured a narrow win in FL-23 during the 2024 presidential election.
- Jared Moskowitz significantly outpaces Oliver Larkin in primary fundraising efforts.
- No specific 2026 general election polling data is available for FL-23.
- Oliver Larkin's potential primary win could significantly affect the general election margin.

Current Context
Florida's 23rd District significantly strengthens for Democrats following recent redistricting. In the 2024 election, Jared Moskowitz (D) secured victory in Florida's 23rd Congressional District (FL-23) with 196,311 votes (52.4%) over Kaufman (R), who received 178,006 votes (47.6%), resulting in an 18,305-vote margin (4.8%) [^][^]. The newly configured FL-23 for the 2026 cycle overlaps with the prior CD-22 and shows a more pronounced Democratic advantage, having recorded 56% support for Harris in 2024 results, indicative of a D+13 lean [^]. Despite broader redistricting efforts by Governor DeSantis that aimed to benefit the Republican Party, FL-23 was strengthened for Democrats [^]. Historically, the district held a Cook Partisan Voting Index (PVI) of D+2 and was rated "Leans Dem" by Sabato's Crystal Ball before the new map; post-redistricting, it is now considered potentially "Safe Dem" [^][^][^].
The upcoming Democratic primary for FL-23 appears very close. A recent poll conducted between February 28 and March 5, 2026, for the August 18, 2026, Democratic primary indicated Oliver Larkin with 45% support, slightly ahead of Jared Moskowitz at 44% [^]. General election predictions from Polymarket currently assign a 60% probability for a Democratic win and 43% for a GOP victory [^]. Key deadlines for the 2026 election cycle include the filing deadline on June 12, 2026, and the voter registration deadline for the primary on July 20, 2026 [^].
2. Market Behavior & Price Dynamics
Historical Price (Probability)
Outcome probability
Date
This market experienced a dramatic and decisive upward trend, fundamentally repricing the probability of a Democratic victory of 2 points or more. The price began at a negligible 2.0% before undergoing a massive 79.0 percentage point spike on or around May 6, 2026, vaulting from 3.0% to 82.0%. This event represents a near-total reversal in market expectations. Following this surge, the price has stabilized at a high of 83.0%, suggesting the market has fully absorbed the new information and established a new baseline expectation.
The primary catalyst for this significant price movement appears to be a major news event: the signing of a new redistricting map. This map is reported to have significantly altered the political landscape of Florida's 23rd District, shifting it to a D+~13 lean. This change makes the "Democrats, 2+ pts" outcome substantially more likely, and the market reacted almost instantly by pricing in this new reality. The price jump effectively created a new support level around the 82-83% mark, where it has remained.
The current price of 83.0% reflects a very strong market consensus that the Democratic candidate will win by the specified margin. The total volume of 1,681 contracts indicates a reasonably active market over its lifetime, lending credibility to the price discovery process. The sharp, vertical price move, followed by a period of stability at a new, high plateau, indicates that traders view the redistricting news as a definitive, game-changing development that has largely settled the question posed by the market.

Notable price changes detected in the chart, along with research into what caused each movement.
Outcome: Democrats, 14+ pts
📈 May 07, 2026: 12.0pp spike
Price increased from 41.0% to 53.0%
What happened: The primary driver of the price spike was the traditional news announcement on May 07, 2026, that Representative Lois Frankel (D) announced her candidacy for Florida's newly redrawn 23rd Congressional District [^][^][^]. This development coincided with redistricting signed in early May 2026, which made the new FL-23 significantly more Democratic, shifting from 52% to 56% Harris 2024 support and being rated "Safe/Lean D" [^][^][^]. Frankel's decision to run in the now more favorable district likely reinforced market expectations for a larger Democratic margin of victory. Based on the provided sources, social media activity appears to have been irrelevant, as no related catalyst was identified on the date of the price move [^][^][^][^][^].
Outcome: Democrats, 2+ pts
📈 May 06, 2026: 79.0pp spike
Price increased from 3.0% to 82.0%
What happened: The primary driver of the 79.0 percentage point spike was a traditional news event: the signing of a new redistricting map on or around May 6, 2026 [^]. This new map reportedly shifted Florida's 23rd Congressional District to a D+~13 lean, making the "Democrats, 2+ pts" outcome significantly more probable [^]. News regarding the changes to Florida's congressional map spiked around May 6-7, 2026, directly coinciding with the prediction market movement [^][^][^]. Social media was not identified as a primary driver based on the provided research.

Market Discussion
Florida's 23rd District, under a new congressional map signed into law on May 6, 2026, is now considered "Safe Democratic" by Sabato's Crystal Ball, with over 56% of voters in the new lines having supported Kamala Harris in the 2024 presidential election [^][^][^][^][^]. While incumbent Jared Moskowitz is expected to run in FL-25, Democrat Lois Frankel is expected to seek election in the new FL-23 and faces a primary challenge from Oliver Larkin on August 18, 2026 [^][^][^][^]. The redrawing has created "chaos" and debate, with some candidates, like Larkin, suggesting the new maps are "illegal" and undermine voter rights [^][^].
5. What do voter registration statistics and 2024 presidential results within the new FL-23 boundaries indicate for the 2026 Democratic margin?
| Cook PVI | D+2 (2025) [^][^] |
|---|---|
| 2024 House Margin | Democratic 4.9 percentage points (52.4-47.6%) [^][^][^] |
| 2024 Presidential Result | Harris narrowly won [^] |
The 2024 elections saw a narrow Democratic victory in FL-23. Kamala Harris secured a narrow win in the district for the presidential election [^]. Concurrently, the 2024 House of Representatives election resulted in a Democratic victory with a margin of 4.9 percentage points, reflecting 52.4% to 47.6% [^][^][^]. Within the district, which encompasses parts of Broward and Palm Beach counties, the Democratic candidate received 54.6% of the vote in Broward, while the Republican candidate received 52.8% in Palm Beach [^][^]. The district’s partisan lean for 2025 is classified as D+2 by the Cook Political Report’s Partisan Voter Index [^][^].
FL-23 previously demonstrated a stronger Democratic preference in 2020. During the 2020 election cycle, the district exhibited a more significant Democratic leaning, with Joe Biden winning by 13 points (56.3%-43.1%) [^]. Looking ahead, Polymarket odds from early 2026 projected a 60% chance for a Democratic hold in the 2026 election, with a 43% chance for a Republican hold [^]. Current voter registration statistics specific to the new FL-23 boundaries were not available in the provided research.
6. Who are the declared Republican candidates for FL-23, and what does their campaign strength suggest for the final margin?
| District Lean | Lean Democratic [^][^][^] |
|---|---|
| Top Fundraiser | Scott Singer, over $1.3 million raised [^] |
| Democratic Presidential Vote Share | Over 56% for Kamala Harris [^] |
The open FL-23 seat leans Democratic with multiple Republican contenders. The FL-23 Congressional District has an open seat due to the Democratic incumbent pivoting to a different district [^]. Several Republican candidates have declared, including George Moraitis, Scott Singer, Darlene Cerezo Swaffer, Raven Harrison, Joe Kaufman, Rafael Ortiz, and Jared Gurfein [^]. The district's new configuration is considered to Lean Democratic [^][^][^], a lean supported by 2024 presidential election results under the new lines, which showed over 56% of voters for Kamala Harris and less than 43% for Donald Trump [^].
Key Republican candidates bring distinct advantages to the primary race. Among the Republican candidates, George Moraitis has received endorsements from multiple Republican U.S. House members [^]. Scott Singer has demonstrated significant fundraising capabilities, raising over $1.3 million [^]. Joe Kaufman has prior experience running in FL-23, having been the Republican nominee in 2024 and challenging the Democratic incumbent in earlier elections [^][^][^][^].
Predicting the final margin remains challenging without specific polling data. While individual candidate strengths such as fundraising [^] and endorsements [^] are noted, the available research does not include specific polling data or head-to-head matchup analyses necessary to directly predict a final margin of victory [^].
7. How do Jared Moskowitz and Oliver Larkin compare on fundraising totals and key policy endorsements ahead of the primary?
| Jared Moskowitz Total Raised | $1.72M (cycle total) [^] |
|---|---|
| Oliver Larkin Total Raised | $327,736 [^] |
| Jared Moskowitz Cash on Hand | $1.21M [^] |
Jared Moskowitz significantly outpaces Oliver Larkin in primary fundraising efforts. Moskowitz has reported a cycle total of $1.72 million, with his total receipts for the 2025-03/2026 period amounting to $1,710,590, which includes $1,582,553 in direct contributions [^]. In the first quarter of 2026 alone, he raised $429,000, contributing to a total cash on hand of $1.21 million [^]. Moskowitz also accepts contributions from PACs, totaling over $323,000 [^][^].
Information regarding the key policy endorsements of either Jared Moskowitz or Oliver Larkin ahead of the primary is not available in the provided research.
8. What public polling data is available for the Florida's 23rd District general election, and what margin of victory does it project?
| 2026 General Election Polling Data | No public polling data available specifically for the 2026 general election margin of victory [^][^][^] |
|---|---|
| Cook Political Report District Rating | Florida's 23rd District is rated "Lean D" with a PVI of D+2 [^][^][^] |
| 2024 General Election Margin | Moskowitz (D) 52.45% vs Kaufman (R) 47.55%, a margin of approximately D+5 [^] |
No specific 2026 general election polling data is available for Florida's 23rd District. Public polling data specifically detailing the projected margin of victory for the 2026 general election in Florida's 23rd District is currently unavailable [^][^][^]. Despite this absence, external analyses provide some insight into the district's leanings. The Cook Political Report assesses Florida's 23rd District as "Lean D" with a Partisan Voter Index (PVI) of D+2, indicating a Democratic advantage [^][^][^]. Furthermore, Polymarket suggests a 60% win probability for Democrats in the upcoming general election [^]. For historical context, the 2024 general election saw the Democratic candidate Moskowitz defeat the Republican candidate Kaufman with 52.45% of the vote compared to 47.55%, resulting in an approximate D+5 victory margin [^].
Primary elections for Florida's 23rd District are scheduled for August 18, 2026. The 2026 primaries for both parties are set for this date [^][^]. An early Democratic primary poll conducted in March 2026 revealed Moskowitz with 45% support, Larkin with 11%, and 44% undecided [^][^][^]. Notably, after candidate biographies were presented to respondents, Larkin's support increased to 49% while Moskowitz's declined to 36% [^][^][^]. Joe Kaufman is among multiple Republican candidates expected to run in their respective primaries for the district [^][^].
9. How might the general election margin be affected if Oliver Larkin defeats incumbent Jared Moskowitz in the August 18 Democratic primary?
| Cook PVI | D+2 [^] |
|---|---|
| 2024 General Election Margin | 4.9% (Moskowitz win) [^][^][^][^] |
| Moskowitz Campaign Funds | $1.7M [^][^] |
Oliver Larkin's potential primary win could significantly affect the general election margin. Florida's 23rd District (FL-23) is considered a swing district with a Cook PVI of D+2 [^], where progressive nominees frequently underperform moderate candidates against Republican opponents. This underperformance is often attributed to factors such as voter turnout and appeal to crossover voters [^]. In 2024, FL-23 was the closest district in Florida, with incumbent Jared Moskowitz securing victory by a narrow 4.9% margin [^][^][^][^].
Larkin challenges Moskowitz in a primary marked by funding and poll differences. The Democratic primary contest between Larkin and Moskowitz shows a notable disparity in campaign funding; Larkin has raised $327,000 through grassroots efforts, whereas Moskowitz has accumulated $1.7 million, despite facing criticism regarding his reliance on PAC funds [^][^]. Primary polls indicate Larkin's competitiveness, with one survey showing him leading 45-44 and a Center for Strategic Politics poll reporting a commanding lead following the release of his biography [^][^]. Should Larkin win, his victory could influence the general election outcome in this swing district, given the historical underperformance of progressive candidates in similar races against Republican candidates [^]. The Republican primary in FL-23 is also crowded, featuring strong fundraisers such as Scott Singer, who has raised $1.3 million [^][^].
