CINCINNATI (AP): A 30-year-old Cincinnati city councilman who says Ohio needs new leaders is launching a 2016 Democratic bid for Republican U.S. Sen. Rob Portman's seat in the swing state.
 
P.G. Sittenfeld says he'll work to help the middle class and supports key initiatives of President Barack Obama including his health care overhaul. Sittenfeld says he'll also have “fresh ideas'' and embrace innovation.
 
He likely will have primary opposition, with several better-known Democrats including former Gov. Ted Strickland considering the race. Sittenfeld says he is has “enormous admiration'' for Strickland, but is focusing on his own effort.
 
Portman, meanwhile, announced Thursday that a veteran Republican strategist known for running aggressive campaigns will be his campaign manager. Corry Bliss is fresh off helping Sen. Pat Roberts win a hotly contested re-election in Kansas.
