Allen County Commissioner Linda Bloom will have to fight to keep her 3rd District seat.
As of Fridays filing deadline, Bloom will face Roy Buskirk and Michael Mills in the May 6 Republican primary.
Bloom has served five terms as a county commissioner, Buskirk has been on the County Council for more than a decade.
Mills faced Buskirk in the 2012 council at-large primary but came in last in a six-way race.
In District 2, Commissioner Therese Brown is unchallenged.
In the race to replace term-limited Allen County Sheriff Ken Fries, Chief Deputy David Gladieux will face Indiana State Police Sgt. Luke NaThalang in the Republican primary. David Roach is unopposed on the Democratic side.
Republican Allen County Assessor Stacey ODay is being challenged by Kimberly Klerner; Democrat Sam Walker is unopposed.
Three Allen County offices are unopposed: Republicans Circuit Court Clerk Lisbeth Borgmann and County Auditor Tera Klutz have no challengers, and Anita Mather is the lone candidate to replace term-limited County Recorder John McGauley.
Thats not the case for County Council District 3, where five Republicans have filed to replace Buskirk.
Travis Armstrong, Gary Washington, Joel Benz, Tom Rotering, and Gwendolyn Sordelet will compete to fill the seat Buskirk vacates as he runs for County Commissioner.
In District 1, Republican Council member Kevin Howell is being challenged by Joe (Fluoride Man) Renner, who often makes presentations lobbying for the removal of fluoride from Fort Waynes municipal water supply. Sharon Tucker is the lone Democrat in the race.
Incumbent Republican Tom Harris is unopposed in District 2, as is Republican Larry Brown in District 4, though he will face Democrat Austin Carpenter in November.
Wayne Township Trustee Rick Stevenson is unopposed, as is Republican Aboite Township Trustee Barbara Krisher, but competition is fierce in St. Joe Township as four Republican candidates are vying to replace Richard Uhrick.
Sarah Gnagy, Barry Kunkle, Ken Richardson and Ed Morris will all face off in the primary.
No Democrats filed.
