Louisiana's 18th State Senate district is one of 39 districts in the Louisiana State Senate. It has been represented by Republican Eddie Lambert since 2016.[3]
District 18 covers parts of Ascension, Livingston, and St. James Parishes to the east of Baton Rouge, including some or all of Gonzales, Sorrento, Prairieville, Killian, and Lutcher.[2]
The district overlaps with Louisiana's 2nd and 6th congressional districts, and with the 58th, 59th, 81st, 88th, and 95th 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.
