When the $20.2 billion state budget was unveiled this week, voting rights advocates got an unpleasant surprise. Although the House and Senate had included $664,000 for the State Board of Elections in their initial spending plans, it mysteriously disappeared from a compromise budget that both chambers approved on Thursday. “When (the budget) went to the conference committee, we kind of thought it was a no-brainer this was going to be in there since both sides had done it,” said Brent Laurenz, executive director of the nonpartisan North Carolina Center for Voter Education.
