Jerry Carl holds the strongest position in the Alabama 1st Congressional District Republican primary race due to his 40.3% finish in the May 19 primary—well ahead of Rhett Marques at 31.1%—which advanced the pair toward a runoff before redistricting litigation intervened. Carl's prior service in the seat through 2024 provides name recognition and established donor networks among Republican primary voters, while Marques leveraged stronger late-2025 fundraising and an early endorsement from Sen. Katie Britt. Ongoing federal court rulings on congressional maps have shifted the contest to an August 11 special primary under revised boundaries that include Mobile and Baldwin counties, narrowing the field and introducing added procedural uncertainty that traders appear to weigh against Carl's early primary momentum.
