Louisiana Debuts New Partisan Primaries As Cassidy Faces Pro-Trump Challenge
Louisiana holds revamped state and federal party primaries on Saturday, May 16, 2026, with Republican U.S. Sen. Bill Cassidy facing a Trump-backed primary challenge.[1]
Cassidy is being challenged by state Treasurer John Fleming and U.S. Rep. Julia Letlow, who has former President Donald Trump's endorsement.[1] Voters will also decide contests for the state Supreme Court, the Public Service Commission and the state school board, plus five constitutional amendments on the ballot.[1]
State Republicans passed legislation on Thursday, May 14, 2026, to restore a November 3 jungle primary format for U.S. House contests.[1] That move came after the state's congressional map was struck down by the U.S. Supreme Court, leaving House races to appear on May 16 ballots even though their votes will not be counted under the court's ruling.[1]
The contests are being watched as an early test of Donald Trump's sway with Louisiana Republicans and as a potential flashpoint for intra-party divisions ahead of the fall.
