The race for the presidency between Hillary Clinton and Donald Trump in Ohio is extremely tight. The Buckeye State's Senate contest is another story. Trump holds a slight 0.6-point edge over Clinton in Ohio currently, according to a RealClearPolitics average of polls. U.S.-based prediction market PredictIt sees Ohio leaning blue, though it has flipped several times in September and October. The Senate race there between Republican incumbent Rob Portman and his Democratic challenger, former Ohio Governor Ted Strickland, appears to be much less contested. RealClearPolitics has Portman with a 15-point lead, and traders give him 90% odds at winning. Republican Senators like Kelly Ayotte in New Hampshire and Ron Johnson in Wisconsin face tough odds at reelection this year, but Senator Portman appears to be largely in the clear. There are many factors working in his favor, including Ohio Governor John Kasich's refusal to back Trump. But it also appears Ohioans are open to doing something voters have been increasingly inclined to avoid: split their tickets. In 2012, only 11% of the U.S. electorate voted for one party's candidate for president and another's for Congress. We might see that number rise in 2016 -- it looks like it could in Ohio.
