**Incumbent Steve Scalise faces minimal opposition in Louisiana’s 1st congressional district jungle primary on November 3, 2026.** The solidly Republican district, rated Safe or Solid Republican by forecasters including Cook, Sabato’s Crystal Ball, and Decision Desk HQ, features Scalise alongside Republican challenger Randall Arrington, Democrat Lauren Jewett, and unaffiliated candidate Liddy Glass. Historical results and current projections show Republican candidates capturing roughly two-thirds of the vote, reflecting the district’s R+19 to R+20 partisan lean and Scalise’s consistent double-digit margins in prior cycles. Recent mid-decade redistricting reinforced this advantage after the Supreme Court ruling in Louisiana v. Callais altered the map. With no competitive polling shifts or major campaign developments in recent weeks, trader consensus assigns a high implied probability to one candidate securing a majority outright and avoiding the December 12 runoff.
