Ohio Senator Mark Mallory announced his candidacy for Cincinnati mayor yesterday. Mallory will join the Democratic ticket, and will take on incumbent Mayor Charlie Luken in next year's primary race. In 2007, Mallory will be forced out of the Statehouse by term limits. He is the son of longtime Ohio legislator William Mallory, Sr. The announcement was made at 1 p.m. yesterday, at a press conference in Columbia Tusculum.
