Glendale Mayor Jerry Weiers and Councilwoman Joyce Clark will face challenges on the Aug. 4 election ballot.
Michelle Robertson filed signatures and nomination paperwork to run against Weiers.
As the city council representative in the Yucca District, Bryce Alexander filed as a candidate. Clark, the incumbent, also filed as a candidate.
Two other council seats are up for election. Incumbents Ian Hugh (Cactus District) and Ray Malnar (Sahuaro District) were the only two to file in their respective districts.
