Incumbent Republican Sen. Bill Cassidy holds a commanding lead in the Louisiana U.S. Senate race, with trader consensus implying 91% odds of a Republican win driven by his consistent polling above 50% in the latest surveys from LSU and others ahead of the November 5 jungle primary. Louisiana's strong Republican lean, evidenced by solid GOP early voting turnout ending October 29 and the state's history of incumbency advantages, positions Cassidy for an outright victory without a December 7 runoff against Democratic challenger Luke Mixon. Recent polls show Cassidy at 55-60% support, widening his margin over the past week amid minimal campaign disruptions. Though exceeding 90%, a late-breaking scandal, depressed turnout, or voting irregularities could force a contested runoff and alter the outcome.
