As key pieces of the legislative agenda get scrutiny in the courts, partisan organizations and politicians are focusing on the race for the one seat up for grabs on the North Carolina Supreme Court. The state’s highest court has a one-vote conservative majority, and that has been reflected in decisions to uphold redistricting maps found unconstitutional in the federal courts and to allow state funds to be used for private school vouchers. Justice Bob Edmunds, who has been on the state’s highest court for 16 years, is a Republican from Greensboro facing a challenge from Wake County Superior Court Judge Mike Morgan, a Democrat from Raleigh. Early voting begins in North Carolina on Oct. 20 and ends Nov. 5. Election day is Nov. 8. The candidates have been going from the coast to the mountains, speaking to individuals and groups. It was not until May that it became clear Edmunds would face any challengers in his campaign to keep his seat.
