Obama campaign spokesman Ben LaBolt responded to the news by posting to Twitter: "Interesting that the GOP is pulling out of NC the day early vote begins and Obama supporters are lined up around the block at the polls."
Obama campaign traveling press secretary Jen Psaki said in North Carolina the Obama campaign has one of their best ground operations in the country.
"We feel confident in our operation there and we're continuing to compete for every single vote," she said on CNN's "The Situation Room with Wolf Blitzer."
Both campaigns poured more ad money into battleground states this week, including North Carolina. At $828,000, Romney's campaign spent less than Obama's campaign at $880,000. The ads run Monday through Sunday.
