Louisiana's 22nd State Senate district

District 22 covers parts of Iberia, Lafayette, St. Landry, and St. Martin Parishes to the east of the city of Lafayette, including some or all of New Iberia, St. Martinville, Breaux Bridge, Port Barre, and Broussard.^[2]

The district overlaps with Louisiana's 3rd and 5th congressional districts, and with 38th, 46th, 48th, 49th, and 96th districts of the Louisiana House of Representatives.^[4]

Louisiana uses a jungle primary system. If no candidate receives 50% in the first round of voting, when all candidates appear on the same ballot regardless of party, the top-two finishers advance to a runoff election.
