Sherrod Brown's seat in the U.S. Senate has long been seen as one of the most likely to flip this election cycle, a loss in Ohio potentially handing Republicans control over the upper chamber. Besides Sen. Jon Tester, D-Mont., Brown is the only other Democrat defending a seat in a deep red state, facing a Trump-backed challenger, Bernie Moreno, who is neck-and-neck in the polls.
"Without Ohio, Democrats have no hope. It's just no way," David Niven, a professor of political science at the University of Cincinnati, said in an interview. "It's hard to imagine they can get to 51, so they're playing for 50 and hoping to have the vice presidency. To get to 50, they need Ohio."
