Marion County will be divided between two Kansas House of Representative districts. Three federal judges issued the new legislative district maps last week.
The county was the population center of its previous legislative district but it will not be the population center in either of the districts it has been split into.
Previously the 70th District encompassed all of Marion and Chase counties and a northern portion of Butler County.
With the new map, the 70th District will include all of Dickinson County except Herington, a small southwestern portion of Clay County, and roughly the northern half of Marion County, excluding Hillsboro.
J. Robert Brookens of Marion is the incumbent in the district, but he will not run for re-election.
John E. Barker of Abilene and Doug Lindahl of Enterprise have filed for the Republican primary in the 70th District.
Hillsboro and the southern half of Marion County will now be part of the 74th District, which includes most of Harvey County, excluding Newton, and the southeast corner of McPherson County.
The 74th District previously consisted of Harvey County except for Newton and all but the northeast quarter of McPherson County.
Incumbent Don Schroeder of Hesston has filed for reelection and is running unopposed.
All of Marion County is now in the 35th Kansas Senate district, represented by Jay Scott Emler of Lindsborg. Previously all of the county but the western edge was in the 17th District, represented by Jeff Longbine of Emporia.
Emler is running for re-election against Jesse Bryant of Galva.
Redistricting was required based on the results of the 2010 U.S. Census.
