Topeka ? Ten Kansas House incumbents have lost primary election races or are trailing in relatively close contests.

But seven of those incumbents faced other incumbents because of political redistricting.

Also, Reps. Clay Aurand, of Belleville, and Rick Billinger, of Goodland, trailed other incumbents in final, unofficial results in their districts. In Wichita, Rep. Jim Ward defeated fellow Democratic Rep. Judy Loganbill.

A GOP race in an Emporia-area district featured three incumbents. Rep. Peggy Mast, of Emporia, defeated Bill Otto, of LeRoy, and Willie Prescott, of Osage City.

Two Republicans were ousted by challengers, Reps. Sheryl Spalding, of Overland Park, and TerriLois Gregory, of Ottawa.

Also, Republican Rep. Carl Dean Holmes, of Liberal, trailed his challenger by seven votes.
