Republican Sen. Rob Portman holds a 10-point lead over his likely Democratic opponent, former Democratic Gov. Ted Strickland, according to a new Vox Populi Polling survey shared exclusively with The Daily Caller.
The Ohio Senate race is shaping up to be a competitive contest, with Democrats arguing Portman is one of the most vulnerable Republican incumbents in the 2016 cycle.
But according to the poll of 474 active voters taken on June 6 and 7, voters prefer Portman over Strickland 47 percent to 37 percent, with 16 percent unsure.
The margin of error in the poll is plus or minus 4.5 percent.
Portman, who has been vetted in recent presidential cycles as a possible Republican running mate, was elected to the U.S. Senate in 2010. He is a former member of Congress, U.S. Trade representative and director of the Office of Management and Budget.
Strickland is a former congressman who served one term as governor of Ohio. In recent years, he has worked for the liberal Center for American Progress.
