Louisiana voters will elect a new U.S. senator to replace Bill Cassidy and choose representatives for all six U.S. House districts, with the Senate race featuring Republican Julia Letlow facing Democrat Jamie Davis.

All six Louisiana U.S. House seats are on the ballot, including incumbents Steve Scalise (1st), Troy Carter (2nd), Clay Higgins (3rd), Mike Johnson (4th), and the open 5th district as Letlow runs for the Senate.

The potential outcome of control in either chamber could shape priorities, committee leadership, and oversight, affecting federal funding and policy on disaster recovery, infrastructure, health care, and education in Louisiana.

In addition to federal races, Louisiana voters will weigh 10 constitutional amendments and other local races, with ballot contents varying by locality.

Nationally, key Senate races of interest include Texas, Ohio, North Carolina, Georgia, and Michigan, which could influence the Senate’s balance of power.

Voters nationwide and in Louisiana will cast ballots on November 3, 2026, to determine control of Congress, with all U.S. House seats and more than one-third of the Senate up for election.

Louisiana’s 6th Congressional District is open, featuring ten candidates including state Senators Blake Miguez and Rick Edmonds; the open-primary system requires a majority to avoid a December 12 runoff.
