Republicans picked up three seats in North Carolina's 2012 congressional elections. The election used districts that had been redrawn by the state's Republican-controlled legislature following the 2010 census. Political gerrymandering is nothing new, but does it thwart the "will of the people" on election day? Researchers at Duke University say a mathematical model they've developed shows that if the exact same votes in 2012 had been cast in differently-drawn districts, the overall results would have changed. WFAE's Mark Rumsey discussed the findings with Jonathan Mattingly, a Duke math professor and one of the study's authors.
