The North Carolina State Board of Elections has rejected a Republican Party request that the board authorize county elections officials to scrutinize signatures on absentee voting documents, citing concerns that the proposal would create unequal standards across counties. The board rejected the request Thursday in a 3-2 party-line vote, with three Democrats voting against signature verification and two Republicans voting in favor. Supporters of the request urged the board to strengthen election security before the November elections when a few hundred votes could be the tipping point in several close races. But voting rights advocates warned the proposal could disenfranchise disabled and elderly voters whose signatures might have changed since they registered to vote.
