Louisiana State Treasurer John Fleming advanced to the June 27 Republican runoff for the U.S. Senate seat after finishing second in the May 16 primary with 28 percent, behind Rep. Julia Letlow at 45 percent and ahead of incumbent Sen. Bill Cassidy. President Trump’s endorsement of Letlow and earlier reported offers of administration roles to Fleming did not prompt his withdrawal before or immediately after the primary. Fleming’s self-funded campaign, prior congressional record, and statewide treasurer position have sustained his position heading into the runoff, where Louisiana’s majority-vote requirement sets a clear path forward. Traders view these factors as evidence that Fleming will remain in the contest through the resolution window.
