**Incumbent Republican Steve Scalise holds a commanding position in Louisiana’s 1st congressional district, a seat with a strong R+19 to R+20 partisan lean and consistent double-digit Republican margins in recent cycles.** Facing limited opposition from Republican challenger Randall Arrington, Democrat Lauren Jewett, and unaffiliated candidate Liddy Glass, Scalise benefits from high name recognition as House Majority Leader, established fundraising, and endorsements including from former President Trump. Nonpartisan ratings classify the race as Solid or Safe Republican, with forecasts projecting Scalise well above 60% and a margin exceeding 30 points. In Louisiana’s majority-vote system, where a candidate needs over 50% on the November 3 first-round ballot to win outright and avoid a December 12 runoff, these factors produce trader consensus around a 95% implied probability of an outright winner. No recent polling or developments indicate a competitive split that would force a second round.
