TOPEKA, Kan. (AP) — Republicans have used their supermajority to win Kansas Senate approval for a redistricting plan that likely would make it harder for the state’s only Democrat in Congress to win reelection this year. The nearly four-hour debate ahead of the Senate’s 26-9 vote Friday previewed the arguments that attorneys for both parties may use during an expected court challenge over any new lines. The bill goes next to the House. Both proposals would carve thousands of Democratic voters out of the Kansas City-area district held by Democratic U.S. Rep. Sharice Davids. Both also would put Lawrence at the far eastern edge of an expanded central and western Kansas district.
