Trump-Backed Letlow Leads Louisiana Senate Primary, Cassidy Out

Louisiana Republicans delivered a clear rebuke to Sen. Bill Cassidy on Saturday, denying the two-term incumbent enough votes to advance in the party's Senate primary. With results showing Rep. Julia Letlow at roughly 45 percent and state Treasurer John Fleming at 28 percent, Cassidy finished third with about 25 percent, falling short of the threshold needed for a runoff.

The outcome followed years of tension stemming from Cassidy's 2021 vote to convict President Donald Trump during his second impeachment trial related to the January 6 Capitol events. Cassidy was one of only seven Senate Republicans to support conviction on charges that Trump incited the riot. Trump responded immediately before polls closed by labeling Cassidy a "disloyal disaster" and a "sleazebag" on social media, urging voters to back Letlow and Fleming instead.

Letlow, whom Trump endorsed earlier this year, led the field and will face Fleming in a June 27 runoff. Both candidates positioned themselves as stronger alternatives on issues ranging from fiscal restraint to opposition to federal diversity initiatives that Cassidy had supported in partnership with Democrats. Fleming, a former Trump administration official, drew support from voters focused on conservative economic priorities, while Letlow highlighted her alignment with the president's agenda on energy and regulatory matters.

Cassidy, a physician by training, had attempted to pivot toward emphasizing cooperation with the administration in recent months. He pointed to votes advancing certain nominees and stressed his legislative record. Yet primary voters appeared unmoved by those efforts, viewing the earlier impeachment decision as a fundamental break with the state's conservative electorate. Turnout patterns showed strong participation among those prioritizing accountability for lawmakers who crossed party lines on high-profile issues.

In his concession remarks, Cassidy stressed that the country centers on the welfare of all Americans and fidelity to the Constitution rather than any single figure. The comments came amid broader primary results that reinforced the durability of Trump's influence within Republican contests, even in states where establishment candidates once held advantages through fundraising and name recognition.

Cassidy had outspent his opponents significantly but could not overcome the lingering effects of his 2021 stance. The race illustrated how incentives in primary elections reward candidates who maintain consistent alignment with voter preferences on core questions of governance and institutional loyalty. Letlow and Fleming now head to a contest that will test whether Trump's backing continues to shape outcomes in the general election for the seat.
