The race for Ohio's 18 electoral votes has tightened, with 51% of likely voters there saying they support President Barack Obama and 47% backing Mitt Romney, according to a CNN/ORC International Poll.
The survey was conducted after last week's presidential debate. Obama's 4-point advantage is within the poll's sampling error.
On a national level, a CNN Poll of Polls that averages three nonpartisan surveys shows that Romney has the support of 48% of likely voters and Obama 47%.
Tune in to CNN TV at 6 p.m. ET as Romney joins Wolf Blitzer on "The Situation Room."
