Westerville, Ohio — Retiring Sen. George Voinovich (R., Ohio.) says he is “not sure” whether the GOP can win the Senate. Speaking outside a local barn, where he was stumping for Republican U.S Senate candidate Rob Portman, Voinovich also voiced support for bipartisan legislating during the lame-duck session. Voinovich says he would like to see the GOP and Democrats “coalesce around a couple of things,” specifically debt reduction. “The American people want us to work together,” he says.
