Roy Cooper's unofficial lead over North Carolina Republican Gov. Pat McCrory has surpassed a key threshold that would block McCrory's request for a statewide recount if its holds.

The Democratic attorney general was ahead of McCrory by more than 10,250 votes as of Wednesday afternoon. His advantage has doubled since election night and grew Wednesday as Wake and Forsyth counties completed their canvass and other counties updated voting tabulations. Six counties haven't finished their canvass.

McCrory's request for a statewide recount would be granted if the margin is 10,000 votes or less after all 100 counties complete their work. North Carolina law does allow the state board to order recounts on its own.

Cooper's campaign cited the updated margin in once again calling on McCrory to concede. McCrory said earlier Wednesday he's letting the elections process play itself out.
