Recent primary results positioned Rep. Julia Letlow as the clear frontrunner for the Republican nomination, with voters advancing her and state Treasurer John Fleming to a June 27 runoff after neither reached a majority. Letlow captured roughly 45 percent of the vote, benefiting from President Donald Trump’s endorsement in a contest that ousted incumbent Sen. Bill Cassidy, who finished third. Traders view Letlow’s primary performance and alignment with party leadership as key factors strengthening her position heading into the runoff, while Fleming trails substantially in implied probability. The outcome remains subject to shifts from campaign developments or turnout in the final weeks.
