Incumbent Republican Steve Scalise secured a decisive majority in Louisiana’s November 3, 2026, open primary for the 1st congressional district, capturing roughly 62 percent of the vote against a Democratic challenger and minor-party candidates. This outcome in a district rated solidly Republican by multiple forecasters reflects the seat’s established partisan lean and the incumbent’s long tenure since 2008. Trader consensus at near-certainty for the Republican reflects the primary results and the absence of a required runoff. Late-stage developments that could still shift resolution include official certification delays, successful legal challenges to vote counts, or unforeseen eligibility issues, though the margin exceeds 28 points and statewide reporting shows no widespread irregularities.
