Robert F. Kennedy Jr. Targets Sen. Bill Cassidy in Louisiana Primary Showdown

Health Secretary Robert F. Kennedy Jr. and his MAHA movement are seeking payback against Republican Sen. Bill Cassidy in next week’s Louisiana primary.

Their goal: unseat Cassidy, whom they view as a symbol of the medical establishment they aim to dismantle.

The big picture: As chair of the Senate HELP Committee, Cassidy has openly opposed Kennedy’s health policy reforms. He previously voted to confirm Kennedy but has since pushed back on his efforts to reduce vaccine recommendations, restructure the CDC, and challenge claims that environmental toxins drive chronic disease.

The most recent clash occurred last week when Cassidy helped block the nomination of Casey Means, a health influencer and close Kennedy ally, for surgeon general. Means is the sister of Calley Means, a top Kennedy adviser.

Kennedy responded with sharp criticism, stating that Cassidy “once again did the dirty work for entrenched interests seeking to stall the MAHA movement and protect the ... status quo.”

Calley Means, who has over 312,000 followers on X, predicted Cassidy would “lose his re-election and immediately work for the pharmaceutical industry who funded his political career.”

Tony Lyons, president of the Kennedy-aligned MAHA PAC, called Cassidy an “existential threat to every child in America” who “must be stopped.”

What They’re Saying

“The gloves are off,” one person familiar with Kennedy’s thinking told Axios.

State of Play

Cassidy faces a May 16 primary challenge from Rep. Julia Letlow and former Rep. John Fleming. Former President Donald Trump endorsed Letlow in January after Cassidy voted to convict Trump during his second impeachment.

Polling Indicates Cassidy’s Vulnerability

A recent Emerson College survey showed Fleming leading with 28%, Letlow at 27%, and Cassidy at 21%. If no candidate secures a majority, a runoff will be held on June 27 between the top two finishers.

The Other Side

A Cassidy campaign insider dismissed Kennedy’s influence, stating, “It’s a totally irrelevant factor. We polled all sorts of MAHA issues and it’s entirely an internet phenomenon.”

However, Louisiana legislators have adopted MAHA-backed policies in the past year, including bans on artificial additives and ultra-processed foods in school meals. Letlow has also aligned herself with MAHA, criticizing Cassidy in March for “stonewalling” Means’ nomination.

What’s Next

Republican operatives are monitoring whether Kennedy will escalate his involvement with a personal visit to Louisiana.
