The closely locked contest reflects deep partisan divisions across the country.
Among true independents, those who say they do not lean toward either party, the share of undecided voters is declining, with each candidate picking up new support at about the same pace. However, Romney maintains a small advantage with the group, with the backing of 41 percent of independents to Obama's 30 percent. Some 21 percent still say they support neither candidate.
Among all voters, 23 percent are undecided or say they have not yet committed to their candidate.
"Considering what the opposition is like, I can do nothing else but vote for Obama," he said. Part of his dislike for the GOP ticket is due to Ryan, he said, describing Romney's ticket mate as "further right that the bulk of the Republican Party." But while he'll vote for Obama, Nugent said he's disappointed in Obama's record.
Robert Hamrick, 39, from Cedartown, Ga., is going the other way. Although a registered Democrat, he plans to vote for the Romney-Ryan ticket, claiming Obama has been deceptive and failed to make good on his promises on the economy, jobs and government debt.
As for Ryan, Hamrick said: "He's very smart. He knows his stuff. He knows the finance. He can take apart Obamacare with ease." Hamrick is a former nursing home manager who left his job about four years ago in hopes of finding one with more security — and has been mostly unemployed ever since.
