TOPEKA, Kan. (AP) -- The Kansas House has postponed debate on proposed new boundaries of the state Senate's 40 districts.

House leaders cited scheduling issues in delaying Wednesday's planned debate until Thursday.

Many legislators believe the map being considered by the House would help conservatives wrest control of the Senate from its moderate GOP leaders in this year's elections.

Conservatives contend a bipartisan redistricting proposal approved last week by the Senate is designed to keep the chamber's current leaders in power.

The dispute over Senate redistricting has stalled action on redrawing House, State Board of Education and congressional districts.

If the impasse drags on, the state could postpone its Aug. 7 primary election.
