NBC: Joe Biden wins North Carolina primary
NBC News projects that former Vice President Joe Biden has won the North Carolina primary.
Biden also won neighboring Virginia on this Super Tuesday.
The North Carolina decision is based on exit polls and projections from NBC because at least two precincts in the state are still open. State election officials say they won't release numbers until all polls are closed.
NBC says Biden rode a wave of support from black voters in the state, as he did on Saturday in South Carolina.
