Four of six proposed amendments will become part of the North Carolina constitution after voters had their say at the polls yesterday. Two of the more controversial state constitutional amendments passed in yesterday’s referendum. About 55 percent of voters approved of the amendment that would require voters to show ID at the polls. And almost 60 percent of voters cleared the way for a 7 percent income tax cap to become enshrined in the state constitution. The amendments to strengthen protections for crime victims and protect hunting and fishing rights also passed. Voters rejected two amendments that would have transferred some of the governor’s appointing powers to the state legislature. The first would have affected judicial appointments. The second would have influenced the makeup of the bipartisan State Board of Elections and Ethics Enforcement. Altogether, four of the republican-backed amendments passed and two failed.
