President Obama and presumptive Republican presidential nominee Mitt Romney are in a statistical tie in Ohio, and the potential addition of home-state Sen. Rob Portman as Mr. Romney’s running mate makes no difference, according to a Quinnipiac University poll released Thursday.
Mr. Obama gets 45 percent to Mr. Romney’s 44 percent in the survey, which has a margin of error of 3 percentage points. The same poll on Feb. 15 had Mr. Obama leading Mr. Romney by 46 percent to 44 percent.
The latest poll found that Mr. Portman wouldn’t move the needle in Ohio as Mr. Romney’s running mate, showing a 45-45 tie between the tickets with the senator included. Fifty-nine percent of Ohioans said they don’t know enough about Mr. Portman to form an opinion.
Republicans never have won the White House without capturing Ohio.
