North Carolina election officials said on Wednesday they did not expect vote totals reported by the state to change for more than a week, as the state remained undecided in both the U.S. presidential race and a Senate seat. "With very few exceptions, North Carolina's election results will not change until Nov. 12 or 13, when all mail-in ballots are received and counted by each county," Karen Brinson Bell, executive director of the state Board of Elections, told a news conference. State officials have been processing some 5.5 million ballots, but there are 117,000 outstanding mail-in ballots - many of which may not have been cast - and an undetermined number of provisional ballots still in the mix.
