Early voting problems in the key battleground state of Ohio are fueling concerns in the final days until Election Day, with the national race essentially tied in the latest Fox News poll.
After several early voters in North Carolina said last week they cast ballots for Mitt Romney but the electronic ballot machine logged their pick as President Obama, similar problems have popped up this week in Ohio.
Voters said they selected Romney on the touch screen but an Obama vote was logged instead.
"You want to vote for who you want to vote for, and when you can't it's irritating," Ohio voter Joan Steven told the Marion Star.
As with the North Carolina cases, election officials had the machine inspected and re-calibrated.
Ohio is widely said to the be the most sought-after state in the two campaign's electoral pathway to the White House because of its 18 electoral votes and nearly even split between Obama and Romney, though Obama has held onto a slight lead in recent polls.
The Fox News poll released Wednesday showed the national matchup tied at 46 percent.
