Kansas Republicans on Tuesday unveiled a proposal to redraw the state’s congressional district boundaries that would give them a substantially better chance at winning all four of the state’s seats in the U.S. House of Representatives by carving up the state’s largest county.

The proposal, introduced by state Rep. Chris Croft (R), would imperil Rep. Sharice Davids (D), who won a district that includes most of the Kansas City metropolitan area in the 2018 midterm elections.

Davids’s district currently includes all of Wyandotte and Johnson counties, two of only five counties in all of Kansas that President Biden carried in the 2020 election.

Croft’s map would divide Wyandotte County, home of Kansas City, into two districts along Interstate 70, giving a substantial number of Davids’s current constituents to neighboring Rep. Jake LaTurner (R). In exchange, Davids’s district would pick up parts of conservative Miami County and all of Franklin and Anderson counties, south and west of the metro area.
