On the ballot
Louisiana switched from the top-two jungle primary to closed/semi-closed partisan primaries for federal races in 2026 (HB 17, first change since 1978). First-round party primaries were held May 16, 2026; no candidate hit 50% in either party, so June 27, 2026 runoffs (after this audit date) will set the nominees: GOP Letlow (44.8%) vs Fleming (28.3%); Dem Crockett vs Davis. Incumbent Bill Cassidy (R) finished 3rd (24.8%) and was eliminated, making this effectively an open seat for the GOP nomination; the four listed are contested runoff candidates, not yet nominees.
