Louisiana Republicans Reject Bill Cassidy After Trump Impeachment Vote

Louisiana Republicans voted Saturday to deny Sen. Bill Cassidy another term in office, marking a major political defeat for one of the seven Republican senators who voted to convict President Trump following the January 6 Capitol riot.

With more than half the vote counted, Cassidy fell behind both Rep. Julia Letlow and State Treasurer John Fleming in the Republican primary. Letlow, who received President Trump’s endorsement earlier this year, led the field with roughly 45% of the vote, forcing a runoff election against Fleming after no candidate secured an outright majority.

Cassidy’s defeat represents another example of President Trump’s continued dominance within the Republican Party as GOP voters increasingly reject lawmakers perceived as disloyal to the president and his America First movement.

President Trump celebrated Cassidy’s struggles throughout the campaign and delivered another sharp attack on the senator as Louisiana voters headed to the polls Saturday.

“Senator Bill Cassidy of Louisiana is a disloyal disaster,” President Trump wrote online. “Bill Cassidy is a sleazebag, a terrible guy, who is BAD FOR LOUISIANA.”

Trump formally endorsed Letlow earlier this year, framing her as a reliable conservative ally who would support the administration’s agenda without hesitation.

Cassidy’s political problems largely stemmed from his February 2021 vote to convict President Trump during the Senate impeachment trial following the Capitol riot. At the time, Cassidy argued Trump was “guilty” of inciting the unrest and attempting to undermine the peaceful transfer of power.

Conservative strategist Ryan Girdusky said the impeachment vote ultimately destroyed Cassidy’s standing with Republican voters.

“The impeachment vote against Trump is really what did him in,” Girdusky said, arguing that many Republican voters viewed the conviction effort as an attempt to permanently block Trump from returning to office.

Letlow campaigned heavily on loyalty to conservative voters and support for President Trump, arguing Louisiana Republicans should never have to question whether their senator would stand with the movement when political pressure intensifies.

During the race, Cassidy and Fleming both attempted to portray Letlow as insufficiently conservative by highlighting previous comments she made supporting diversity and inclusion efforts. Critics argued ideological differences between the candidates were smaller than the campaign rhetoric suggested.

Cassidy also drew backlash from many Trump allies for resisting several administration nominees, including surgeon general candidate Casey Means. Cassidy, who chairs the Senate health committee, stopped short of fully backing her nomination, angering supporters of the MAHA movement and drawing criticism from President Trump himself.

Meanwhile, the White House is already turning attention toward other Republican primary battles involving lawmakers viewed as insufficiently loyal to President Trump. Among the next major targets is Rep. Thomas Massie, who now faces a Trump-backed challenge from retired Navy SEAL Captain Ed Gallrein in Kentucky.

Political observers say Cassidy’s defeat reinforces President Trump’s status as the dominant force inside the Republican Party heading into the next election cycle, particularly in deeply conservative states where voter loyalty to the president remains extremely strong.
