Redistricting
2020 redistricting cycle
Kansas enacted legislative district boundaries on May 18, 2022, when the Kansas Supreme Court unanimously upheld the validity of the legislative districts that Kansas Gov. Laura Kelly (D) signed into law on April 15, 2022.[7][8] Both chambers of the legislature passed the redistricting legislation on March 30, 2022, after a joint House-Senate conference committee had developed it.[9] The Kansas House of Representatives approved the legislative boundaries, 83-40, and the State Senate approved them, 29-11.[9]After Kelly signed the maps, Andrew Bahl and Rafael Garcia of the Topeka Capital-Journal wrote, "The state Senate and House maps were mildly contested in the Legislature, particularly in the Senate where the map will create a fourth, Democrat-leaning district in Topeka and Lawrence."[10]
How does redistricting in Kansas work? In Kansas, the state legislature draws both congressional and state legislative district lines. Redistricting plans are subject to veto by the governor. State legislative district maps must be submitted for final approval to the Kansas Supreme Court, which must determine whether the maps are constitutional. If the court rules that the maps violate the law, the state legislature may attempt to draw the lines again. There are no such provisions in place for congressional redistricting.[11]
In 2002, Kansas adopted guidelines for congressional and state legislative redistricting. These guidelines ask that "both congressional and state legislative districts be contiguous, as compact as possible, and recognize and consider communities of common 'social, cultural, racial, ethnic, and economic' interests." In addition, these guidelines stipulate that state legislative districts should "preserve existing political subdivisions and avoid contests between incumbents to the extent possible." Congressional districts should "preserve whole counties and maintain the core of existing districts where possible." The state legislature may amend these guidelines at its discretion.[11]
