Louisianans are heading to the polls this Saturday for the state’s Senate primaries, featuring a high-stakes battle for the Republican nomination. Incumbent Senator Bill Cassidy is fighting to secure a third term as he faces challenges from within his own party.
A Divided GOP Primary
The Republican contest has evolved into a competitive face-off between Sen. Cassidy and Rep. Julia Letlow. Letlow, 45, who became the first Republican woman elected to represent Louisiana in Congress in 2021, has positioned herself as the more loyal conservative candidate.
Letlow won a special election for Louisiana’s 5th Congressional District following the 2020 death of her husband, who died from COVID-19 complications before he could be sworn into office. She has criticized Cassidy as disloyal to the GOP, arguing that the state “shouldn’t have to wonder how our senator will vote when the pressure’s on.”
The Influence of the Presidency
The race is being viewed as a significant test of the president’s influence over the party. On Saturday morning, the president used Truth Social to slam Cassidy, calling him a “disloyal disaster” and citing his 2021 vote to convict the president in an impeachment trial following the Jan. 6 Capitol attack.
The president endorsed Letlow in January, describing her as “a winner who will NEVER let you down.” This follows a similar pattern seen earlier this month in Indiana, where efforts to remove state senators who defied presidential redistricting goals were largely successful.
Policy Clashes and Third-Party Contenders
Beyond the impeachment vote, Cassidy, a medical doctor, has clashed with the administration over the leadership of Health and Human Services Secretary Robert F. Kennedy Jr. While Cassidy provided the key vote to advance Kennedy’s nomination last year, he has since criticized the HHS secretary regarding the postponement of vaccine advisory panel meetings and changes to the hepatitis B vaccine schedule for infants.

Cassidy has countered Letlow’s claims of insufficient conservatism by pointing to her 2020 comments supporting DEI programs in education. The friction between the two main candidates has also created an opening for State Treasurer John Fleming, a former House representative who served in the first Trump administration.
Institutional Support vs. Party Endorsement
Despite the presidential opposition, the National Republican Senatorial Committee (NRSC) has backed Cassidy. Senate Majority Leader John Thune described Cassidy as a “terrific senator for Louisiana,” noting that the NRSC’s role is to support incumbents, though the final decision rests with the voters.
The Democratic Race and General Outlook
On the Democratic side, candidates Nick Albares, a former policy advisor to Gov. John Bel Edwards; Navy veteran Gary Crockett; and third-generation farmer Jamie Davis are competing for the nomination.
However, the general election may be less competitive. Louisiana is considered a solidly red state, with the president winning 60% of the vote in 2024. Because the state has not elected a Democrat to the Senate since 2008, the GOP primary winner is likely to have a glidepath to the seat in November.
What Happens Next
The immediate outcome depends on whether any candidate secures a simple majority on Saturday. If no one reaches that threshold, the top two vote-getters may proceed to a runoff election on June 27. An April poll from Emerson College indicates that a runoff is a likely outcome.

Meanwhile, other state elections are in flux. Republican Gov. Jeff Landry suspended the state’s House primaries after the Supreme Court struck down the state’s congressional map earlier this month, though the Senate primaries were allowed to proceed as planned.
