The North Carolina State Board of Elections has found thousands of instances of voter fraud in the state, thanks to a 28-state crosscheck of voter rolls. Initial findings suggest widespread election fraud.

765 voters with an exact match of first and last name, DOB and last four digits of SSN were registered in N.C. and another state and voted in N.C. and the other state in the 2012 general election.
35,750 voters with the same first and last name and DOB were registered in N.C. and another state and voted in both states in the 2012 general election.
155,692 voters with the same first and last name, DOB and last four digits of SSN were registered in N.C. and another state – and the latest date of registration or voter activity did not take place within N.C.

That would be my guess. There is no way the black vote came out a second time, they had to fake it.
