FAYETTEVILLE, N.C. — When a federal appeals court overturned much of North Carolina’s sweeping 2013 election law last month, saying it had been deliberately intended to discourage African-Americans from voting, something else was tossed out as well: the ground rules for this year’s elections in a critical swing state. In each of the state’s 100 counties, local elections boards scheduled new hearings and last week filed the last of their new election rules with the state.

Now, critics are accusing some of the boards, all of which are controlled by Republicans, of staging an end run around a court ruling they are supposed to carry out. Like the law that was struck down, say voting rights advocacy groups and some Democrats who are contesting the rewritten election plans, many election plans have been intentionally written to suppress the black vote.

“It is equal to voter suppression in its worst way,” said Courtney Patterson, the sole Democrat on the Lenoir County elections board.

He was referring to a proposal by the board’s two Republicans to allow 106.5 hours of early voting before the Nov. 8 election — less than a quarter of the time allowed in the 2012 presidential election — and to limit early balloting to a single polling place in the county seat of a largely rural eastern North Carolina county that sprawls over 403 square miles.
