Louisiana Senate Primary

The race to fill Louisiana's Class II Senate seat is set. After months of primaries and runoffs, the nominees for the 2026 Louisiana U.S. Senate election are confirmed: Republican Julia Letlow and Democrat Jamie Davis will face each other on November 3. The road to get here was anything but quiet; it included the fall of a two-term incumbent, a bitter intra-party battle, and an underdog Democrat who won every single parish in the state. Here's what Louisiana voters need to know.

Primary Candidates

Julia Letlow

Julia Letlow enters the general election as the clear frontrunner for the Louisiana Class II Senate seat.

Letlow currently serves as U.S. Representative for Louisiana's 5th Congressional District, a position she has held since 2021. She made history as the first Republican woman to represent Louisiana in the U.S. House.

Her path to the Republican nomination was built on two pillars: Trump's endorsement, which she received in January 2026 before she had even formally entered the race, and the backing of Republican Gov. Jeff Landry. Letlow made those endorsements the centerpiece of her campaign, framing her opponents, including both Cassidy and Fleming, as insufficiently loyal to Trump.

Her platform focuses on conservative priorities: border security, faith, family, and close alignment with the Trump administration's agenda.

In the runoff, she defeated Fleming by roughly 14 points.

Jamie Davis

On the Democratic side of the 2026 Senate race in Louisiana, Jamie Davis emerged as the nominee after a surprisingly dominant primary performance.

Davis is a farmer and former Tensas Parish Police Juror, a local government position in Louisiana's parish system. He is not a career politician, and he ran on a straightforward economic message: lower costs, protect rural hospitals, and put Louisiana first.

What made his primary performance notable was its geographic breadth. Davis won the Democratic primary in all 64 Louisiana parishes, a sweep that suggests he connected with Democratic voters across the state, not just in urban centers. He then won the Democratic runoff with nearly 80% of the vote.

The Money Behind the Race

With nominees set and the general election scheduled for November 3, here are the key things to keep an eye on in the months ahead:

More than $15.3 million in outside spending flowed into this race through the primary and runoff stages, with the vast majority (over $14 million) directed at or against Julia Letlow. The Louisiana Freedom Fund and the Accountability Project were the top outside spenders. Expect that number to grow as the general election approaches.

While Louisiana itself is not considered competitive, the outcome contributes to the overall balance of power in the U.S. Senate. Republicans are heavily favored to hold this seat.

Whether the Democratic nominee can make this race even modestly competitive will depend on whether his rural, working-class economic message gains any traction in a state where Democrats have struggled for years.

Ratings vs. Odds

Louisiana is one of the most reliably Republican states in the country, and this race is rated Solid Republican by Cook Political Report, Sabato's Crystal Ball, and Inside Elections. The prediction market platform Kalshi, as of July 10, put the probability of a Republican win at 94.2%, with about $84,700 in trading volume behind that figure.

Prediction markets give Davis roughly a 1-in-17 chance of winning. Davis's path to victory would require an extraordinary political environment, one that, as of now, forecasters do not see materializing.

For now, Julia Letlow is the prohibitive favorite to become Louisiana's next U.S. Senator. But November is still months away, and voters will have their say on November 3.
