Voters in Wake County's District 3 have one more school board vote to cast. Democrat Kevin Hill and Republican Heather Losurdo will face off in a runoff election on Tuesday. The result will decide which party will rule when the new school board takes office in December. It's been a long campaign season, and the Wake schools debate continues to attract national attention. Host Frank Stasio talks with WUNC reporter Dave DeWitt about the election and the new student assignment plan at the heart of the controversy.
