Louisiana Election Guide: US House, Senate and Constitutional Races
Voters in Acadiana and Southwest Louisiana Shape House and Senate Races on November 3, 2026
The ballot sets the direction for federal representation in two key congressional districts while shaking up local politics following the departure of Bill Cassidy in the May primary.
District 3 brings a contested Republican primary matchup along the state’s coastal areas and parts of Acadiana. Clay Higgins faces Kate Cotten of Lake Charles. Cotten entered the race to provide Republican voters an alternative choice, though her campaign maintained a low profile. Meanwhile, Democratic candidate Priscilla Gonzalez mounts another bid for the seat after finishing second in the 2024 election. Gonzalez enters voting day shadowed by a recent complaint filed with the state ethics board regarding alleged campaign finance violations.
District 4 stretches northward from Calcasieu Parish to Shreveport. Incumbent Speaker of the House Mike Johnson defends his seat against a mixed slate of Democratic and Republican challengers.
The statewide U.S. Senate race draws intense focus as current U.S. Representative Julia Letlow seeks to fill the seat left vacant by Cassidy’s primary defeat. Letlow faces Jamie Davis, a farmer and small business owner from Tensas Parish running as the Democratic candidate. Initial expectations positioned Letlow as a favorite, but recent polling data indicates Davis running a tighter race than anticipated.
Ten Proposed State Constitutional Amendments on the Ballot
Beyond candidate races, the November 3 ballot asks voters to weigh in on 10 separate changes to the state’s governing document. The proposed amendments cover property tax exemptions, mandatory sentencing rules, and term limits for governors. An in-depth explanation of each proposal appears in The Current’s voter guide.
Tuesday’s results will shape the national balance of power in Washington while altering local governance across Calcasieu Parish, Shreveport, and the Acadiana region.
