Mann, 49, will oppose current city council member Darcy Kuenzi in the race for mayor. Voters will elect the mayor in at at-large vote to serve a two-year term. The other council members are elected in four separate districts.
"The current council majority has stifled public debate, lacks transparency, and has cultivated a perception throughout the community that city hall is unresponsive," Mann said in a press release.
This will be the first time the mayor will be determined by a popular vote rather than a vote of the council members. A 2010 referendum approved by voters changed the mayoral voting system in Menifee, which was incorporated in 2008.
Mann served two years on the first Menifee City Council before losing to Tom Fuhrman in 2010. He is a business consultant who spent 25 years in the Navy.
