Cory Bowman, who shares a father with Vance, says he was inspired to enter the race after his half-brother's inauguration. A Republican last ran for Cincinnati mayor, unsuccessfully, in 2009.

Two Republicans challenged incumbent Cincinnati Mayor Aftab Pureval, a Democrat, in the nonpartisan primary.

Cory Bowman will next face Aftab Pureval, the Democratic incumbent, who outperformed him in Tuesday’s nonpartisan primary.
