Trader consensus centers the 1.4M-1.5M turnout band as the modal outcome because Louisiana’s roughly 2.97 million registered voters historically produce 45-50 percent participation in non-presidential Senate contests. Recent primary and runoff voting in May and June 2026 generated only about 513,000 ballots statewide, underscoring limited baseline enthusiasm in a race rated solid Republican. With Julia Letlow holding a double-digit polling edge over Jamie Davis, the contest lacks the mobilization pressure seen in closer battlegrounds. Early voting begins October 20 and ends October 27 ahead of the November 3 election, providing a standard window that typically captures a modest share of the electorate without extraordinary weather, legal, or national events altering participation. These structural and timing factors keep adjacent ranges at 1.3M-1.4M and 1.5M-1.6M as secondary possibilities while capping odds on higher or lower extremes.
