In Alabama's 1st Congressional District Republican primary set for March 5, trader consensus reflects a dead heat among incumbent Jerry Carl and challengers James Dees, Rhett Marques, and John Mills, all hovering near 40% implied probability per recent polls showing no clear frontrunner. Carl's incumbency advantage is offset by Dees' strong fundraising—over $1 million raised—and aggressive advertising highlighting Carl's perceived moderate stances on issues like border security. A February internal poll for Dees showed him edging Carl 29%-27%, with Marques and Mills in single digits but gaining from veteran endorsements and grassroots turnout efforts. Early voting underway could favor high-propensity conservatives, while a late Trump endorsement or final debate performance might tip the balance in this low-turnout primary.
