A former Ohio governor has won the Democratic U.S. Senate nomination in Ohio for the Republican-held seat.

Ted Strickland handily held off a spirited challenge by Cincinnati councilman P.G. Sittenfeld, who argued that state Democrats needed fresh faces and ideas. Strickland had 69 percent of the vote to 20 percent for Sittenfeld and 10 percent for Cincinnati occupational therapist Kelli Prather with 7 percent of precincts reporting unofficial returns.

Incumbent Rob Portman easily won nomination to seek a second term in what’s already a hotly contested battle with Strickland.

Democrats have targeted swing-state Ohio as among the places where they could win a Senate seat in their quest to retake a majority.
