Incumbent Steve Scalise faces limited opposition in Louisiana’s 1st congressional district jungle primary on November 3, 2026, from Republican challenger Randall Arrington, Democrat Lauren Jewett, and unaffiliated candidate Liddy Glass. The district’s consistent Republican lean, reflected in its R+19 to R+20 partisan voting index and Scalise’s prior outright victories including 66.8% in 2024, supports expectations of a majority in the first round. Nonpartisan ratings classify the seat as Solid or Safe Republican, with no recent polling shifts, candidate withdrawals, or developments indicating vote fragmentation sufficient to force a December runoff. Trader consensus on an outright winner aligns with these structural factors and the absence of competitive dynamics that have produced runoffs in other Louisiana races.
