According to Public Policy Polling (pdf):

Democrat Sen. Barack Obama has pulled into a tie with Republican John McCain in North Carolina, according to results released by Public Policy Polling Saturday.

Each candidate has 46 percent and Libertarian Bob Barr had 5 percent.

North Carolina has voted for Republican presidential candidates for the past three decades.

Obama’s standing in the state has improved over the year as more voters are citing concern over the economy as a top issue when deciding who to vote for, according to the PPP.

“The more voters are concerned about the economy instead of things like immigration, taxes and social issues, the better Democrats are going to do in North Carolina” PPP president Dean Debnam said in a press release.
