| John Fleming | 30.0% | 26.5% | The former U.S. Representative commands significant name recognition and a loyal Republican base. |

## Market Behavior & Price Dynamics

This market exhibits a prolonged sideways or range-bound trading pattern, with the probability fluctuating between a support level around 7% and a resistance level near 18%. The price started at 9.0% and is currently trading at 8.1%, indicating very little net change over the life of the market and reinforcing the lack of a clear directional trend. The most significant movement was the climb to the 18.0% peak, but the price was unable to sustain that level and has since returned to the lower end of its established trading range. Without specific news events provided in the context, these price swings appear to be driven by internal market dynamics and shifts in trader positioning rather than reactions to external catalysts.

The total trading volume of over 10,000 contracts suggests a reasonable level of engagement, but the price action's confinement to a narrow, low-probability band indicates a lack of strong conviction from traders. The market is not consolidating in anticipation of a major move higher or lower; rather, it reflects a persistent state of uncertainty. The current price of 8.1%, near the historical support level of 7.1%, suggests that immediate sentiment is slightly bearish or, at a minimum, lacks any bullish momentum. Overall, the chart indicates that the market consistently views this outcome as a low-probability, long-shot event, with traders having been unwilling to price it above 18% at any point.

## Contract Snapshot

This contract resolves to "Yes" if Julia Letlow wins the Republican Party nomination for the 2026 Louisiana Senate seat, and "No" otherwise. The outcome will be verified from the Republican Party (lagop.com). The market, which opened on January 17, 2026, closes either upon Letlow securing the nomination or by November 3, 2026, 10:00 AM EST, with payouts expected 30 minutes after closing.

## Market Discussion

Traders on this market heavily favor Julia Letlow for the Louisiana Republican Senate nomination at 63%, while John Fleming holds 30% and incumbent Bill Cassidy is at 8.1%. Arguments for Fleming's potential include visible yard sign support and claims of him leading in some polls, while negative sentiment is expressed against Cassidy's political actions. A notable discussion also clarifies that Louisiana's partisan primaries still feature runoffs if no candidate secures a majority.

## How did Louisiana conservative media react to Bill Cassidy's impeachment vote?

Moon Griffon's Accusation | Stated Cassidy "lied" and committed "political suicide" [[^]](https://www.theadvocate.com/baton_rouge/news/politics/elections/bill-cassidy-broke-with-gop-on-trump-impeachment-trial-vote-and-republicans-arent-happy/article_3725259a-6bf9-11eb-8598-4311d899de03.html) |

**Louisiana conservative media strongly criticized Senator Bill Cassidy's impeachment vote**

Louisiana conservative media strongly criticized Senator Bill Cassidy's impeachment vote. Following Senator Bill Cassidy's vote to convict former President Donald Trump in the 2021 impeachment trial, Louisiana-based conservative media outlets launched significant criticism. The Hayride, a prominent conservative blog in Louisiana, explicitly called for Senator Cassidy to resign from office as a direct response to his vote, demonstrating strong disapproval [[^]](https://www.theadvocate.com/baton_rouge/news/politics/elections/bill-cassidy-broke-with-gop-on-trump-impeachment-trial-vote-and-republicans-arent-happy/article_3725259a-6bf9-11eb-8598-4311d899de03.html). Talk radio host Moon Griffon was another vocal critic, asserting that Cassidy had "lied" to voters during his campaign just months prior to the impeachment vote and stating his belief that Cassidy had committed "political suicide" by voting to convict [[^]](https://www.theadvocate.com/baton_rouge/news/politics/elections/bill-cassidy-broke-with-gop-on-trump-impeachment-trial-vote-and-republicans-arent-happy/article_3725259a-6bf9-11eb-8598-4311d899de03.html).

Initial strong criticisms were not accompanied by specific spending data. Although Griffon later acknowledged being "wrong" about Cassidy in a more recent context, his initial messaging directly after the impeachment vote was unequivocally negative [[^]](https://kpel965.com/moon-griffon-says-he-was-wrong-about-bill-cassidy-as-he-apologizes-to-this-city). The available sources do not provide specific data or statistics regarding the spending levels of these or other Louisiana-based conservative PACs and media outlets explicitly targeting Bill Cassidy's 2021 impeachment vote [[^]](https://www.theadvocate.com/baton_rouge/news/politics/elections/bill-cassidy-broke-with-gop-on-trump-impeachment-trial-vote-and-republicans-arent-happy/article_3725259a-6bf9-11eb-8598-4311d899de03.html).

## How Do Louisiana Senate Candidates Align with Jeff Landry's Staff?

Letlow's Key Consultant | Kyle Ruckert, former campaign manager for Jeff Landry's 2023 gubernatorial bid [[^]](https://www.nola.com/news/politics/jeff-landry-announces-louisiana-governor-transition-team/article_ca452780-734e-11ee-85b5-679f2c91a644.html) |
Ruckert's Role for Landry | Instrumental in Landry's gubernatorial victory and former Chief of Staff [[^]](https://theadvertiser.com/story/news/2026/03/02/julia-letlow-builds-senate-campaign-team-with-familiar-faces-in-louisiana-politics-backed-by-trump/88948564007/) |
Fleming's Stance on Landry | Accused Landry of interference in Louisiana Senate race [[^]](https://www.knoe.com/2026/03/04/state-treasurer-john-fleming-accuses-jeff-landry-interfering-louisiana-senate-race/) |

**Julia Letlow has notably hired key staff from Governor Landry's campaign**

Julia Letlow has notably hired key staff from Governor Landry's campaign. Julia Letlow has brought on Kyle Ruckert as a top consultant for her Senate campaign [[^]](https://theadvertiser.com/story/news/2026/03/02/julia-letlow-builds-senate-campaign-team-with-familiar-faces-in-louisiana-politics-backed-by-trump/88948564007/). Ruckert served as Governor Jeff Landry's campaign manager during his successful 2023 gubernatorial bid [[^]](https://www.nola.com/news/politics/jeff-landry-announces-louisiana-governor-transition-team/article_ca452780-734e-11ee-85b5-679f2c91a644.html) and subsequently held the position of his Chief of Staff [[^]](https://theadvertiser.com/story/news/2026/03/02/julia-letlow-builds-senate-campaign-team-with-familiar-faces-in-louisiana-politics-backed-by-trump/88948564007/). He is widely recognized as having been "instrumental in Landry's gubernatorial victory" [[^]](https://theadvertiser.com/story/news/2026/03/02/julia-letlow-builds-senate-campaign-team-with-familiar-faces-in-louisiana-politics-backed-by-trump/88948564007/) and has also taken on a leadership role within Landry's Political Action Committee [[^]](https://www.wbrz.com/news/chief-of-staff-kyle-ruckert-leaves-governor-s-office-moves-to-leadership-role-at-landry-s-pac/). These hires signal a strong alignment between Letlow's campaign and Governor Landry's political network.

John Fleming has not hired Landry staff and has publicly criticized him. Conversely, State Treasurer John Fleming has not reportedly hired any staff or consultants from Governor Landry's 2023 campaign. Instead, Fleming has openly criticized Jeff Landry, accusing him of interfering in the Louisiana Senate race [[^]](https://www.knoe.com/2026/03/04/state-treasurer-john-fleming-accuses-jeff-landry-interfering-louisiana-senate-race/). This difference in staffing choices and public statements suggests a clear contrast in political strategy and alignment between Fleming and Governor Landry's political apparatus, further underscored by Fleming being targeted by outside groups in the context of the Senate race [[^]](https://www.nola.com/news/politics/two-outside-groups-hit-john-fleming-in-louisiana-senate-race/article_58843855-8133-4c36-ad78-67c7dbb5ffea.html).

## What Were John Fleming and Julia Letlow's First Quarter 2025 Contributions?

John Fleming Q1 2025 Total Contributions | $715,310 [[^]](https://www.thedeadpelican.com/2024/flemingmoney.html) |
John Fleming Q1 2025 In-State Donors | More than 80% [[^]](https://shreveporttimes.com/story/news/2025/04/16/millions-flowing-in-2026-louisiana-senate-election-campaign-with-incumbent-bill-cassidy/83119231007) |
Julia Letlow Q1 2025 New Contributions | Approximately $50,000 [[^]](https://shreveporttimes.com/story/news/2025/04/16/millions-flowing-in-2026-louisiana-senate-election-campaign-with-incumbent-bill-cassidy/83119231007) |

**John Fleming raised significant funds without Super PAC support in Q1 2025**

John Fleming raised significant funds without Super PAC support in Q1 2025. During the first quarter of 2025 (January 1 to March 31), John Fleming's campaign committee, "Fleming for Louisiana," reported raising **$715,310** [[^]](https://www.thedeadpelican.com/2024/flemingmoney.html). A substantial portion, exceeding **80%**, of his individual contributions came from Louisiana residents [[^]](https://shreveporttimes.com/story/news/2025/04/16/millions-flowing-in-2026-louisiana-senate-election-campaign-with-incumbent-bill-cassidy/83119231007). Notably, his campaign committee reported receiving no contributions from political action committees (PACs), including national conservative Super PACs, during this period [[^]](https://www.thedeadpelican.com/2024/flemingmoney.html).

Julia Letlow secured new funds and retained substantial cash on hand. Her campaign committee, "Julia Letlow for Congress," reported approximately **$50,000** in new contributions for the first quarter of 2025 [[^]](https://shreveporttimes.com/story/news/2025/04/16/millions-flowing-in-2026-louisiana-senate-election-campaign-with-incumbent-bill-cassidy/83119231007). She also maintained a considerable cash on hand balance of **$1.2** million, largely carried over from her prior congressional campaign [[^]](https://shreveporttimes.com/story/news/2025/04/16/millions-flowing-in-2026-louisiana-senate-election-campaign-with-incumbent-bill-cassidy/83119231007). Similar to Fleming, Letlow's Q1 2025 report does not indicate any contributions from Super PACs to her campaign committee [[^]](https://shreveporttimes.com/story/news/2025/04/16/millions-flowing-in-2026-louisiana-senate-election-campaign-with-incumbent-bill-cassidy/83119231007). A detailed breakdown distinguishing in-state versus out-of-state donors for Letlow's new contributions in this quarter is not available in the provided summary data [[^]](https://shreveporttimes.com/story/news/2025/04/16/millions-flowing-in-2026-louisiana-senate-election-campaign-with-incumbent-bill-cassidy/83119231007).

## Which Louisiana GOP figures advocate consolidating the field to block a Democrat?

Specific calls for strategic consolidation | No explicit public calls identified from specific figures or committees for this reason [[^]](https://punchbowl.news/article/campaigns/la-senate-primary/) |
General Republican concern | Crowded field could allow a Democrat into the top-two runoff [[^]](https://punchbowl.news/article/campaigns/la-senate-primary/) |
Bossier Parish Republican Committee | Urged "unity within the party to unseat incumbent Sen. Bill Cassidy" [[^]](https://www.shreveportbossieradvocate.com/news/bossier-republican-committee-endorses-candidate-in-contentious-u-s-senate-race/article_975ba351-0614-4ed9-ab57-68df818f9f5f.html) |

**No specific figures call for consolidation to prevent a Democrat**

No specific figures call for consolidation to prevent a Democrat. Based on web research, no individual Louisiana political figures or parish-level GOP committees have been explicitly identified as publicly advocating for consolidating the Republican field behind a single challenger to Senator Bill Cassidy with the strategic intent of preventing a Democrat from securing a top-two spot in the jungle primary. Nevertheless, a general concern persists among Republicans that a crowded field could potentially allow a Democrat to advance to a runoff [[^]](https://punchbowl.news/article/campaigns/la-senate-primary/).

Calls for unity lack specific anti-Democrat motivation. While the Bossier Parish Republican Committee has publicly urged "unity within the party to unseat incumbent Sen. Bill Cassidy" [[^]](https://www.shreveportbossieradvocate.com/news/bossier-republican-committee-endorses-candidate-in-contentious-u-s-senate-race/article_975ba351-0614-4ed9-ab57-68df818f9f5f.html), the stated motivation in that source does not explicitly link this call for unity to the specific goal of preventing a Democrat from reaching the top-two runoff.

## How Did Julia Letlow Secure Key Endorsements?

**Julia Letlow successfully secured Donald Trump's significant endorsement**

Julia Letlow successfully secured Donald Trump's significant endorsement. Julia Letlow, a Republican challenger in the Louisiana U.S. Senate race, has obtained an endorsement from former President Donald Trump [[^]](https://www.theadvocate.com/baton_rouge/news/politics/president-trump-endorsed-julia-letlow-for-senate-race/article_9a2a55c7-57e3-5f5c-9f51-fcb47c36d2c2.html). This backing is considered highly significant for candidates vying in Republican primaries [[^]](https://www.nola.com/news/politics/louisiana-us-senate-race-republicans-want-trumps-backing/article_6a8e5580-1259-4a68-a6d7-1ee5decaabc2.html).

Governor Jeff Landry's support aided Letlow's campaign significantly. A primary measurable action that contributed to or reinforced Letlow's standing with Trump has been the active support from Louisiana Governor Jeff Landry [[^]](http://theadvocate.com/baton_rouge/news/politics/elections/jeff-landry-julia-letlow-bill-cassidy-fundraising-endorsements/article_d689ba64-fcbc-506a-a40d-7f4cccb5b4e0.html). Governor Landry, a notable ally of Donald Trump, formally endorsed Letlow [[^]](https://shreveporttimes.com/story/news/2026/02/13/governor-jeff-landry-and-trump-loom-large-in-heated-louisiana-senate-race-with-bill-cassidy/88659634007/) and has provided assistance to her campaign against incumbent Senator Bill Cassidy [[^]](http://theadvocate.com/baton_rouge/news/politics/elections/jeff-landry-julia-letlow-bill-cassidy-fundraising-endorsements/article_d689ba64-fcbc-506a-a40d-7f4cccb5b4e0.html).

Other challengers seek Trump's backing; Scalise remains uncommitted. While other Republicans in the race have publicly expressed their desire to win Trump's backing [[^]](https://www.theadvocate.com/baton_rouge/news/politics/louisiana-us-senate-race-republicans-want-trumps-backing/article_306c3d2e-9fff-5cd3-89f1-9b963920a7a5.html), the available information primarily details Letlow's successful attainment of the endorsement and the specific support she received from Governor Landry. It is also notable that House Leader Steve Scalise has not endorsed the incumbent Senator Bill Cassidy [[^]](https://www.nola.com/news/politics/elections/steve-scalise-wont-endorse-sen-bill-cassidy/article_d310d768-b3d6-41e0-97f3-0dce9c616729.html).
