On the same day, mayoral candidate John Cranley proposed a debate soon over the issue of privatizing parking meters, his opponent, Vice Mayor Roxanne Qualls, proposed a series of five post-primary debates - after council has acted on the parking issue.
Cranley, a former city council member, opposes the plan - which has yet to be formally introduced in Cincinnati City Council - while Qualls is a supporter.
Libertarian Jim Berns has filed petitions to run for Cincinnati mayor, setting up what will be the first mayoral primary election in the city since 2005.
Democrats Roxanne Qualls, a former mayor and now vice mayor, and former council member John Cranley have not filed their petitions yet, but are actively campaigning and raising money and plan to file petitions by the June filing deadline.
Berns' entry into the race guarantees a primary election in the city of Cincinnati on Sept. 10; and it will be a costly one.
