Republican voters in SC, Democrats in Nevada in spotlight

The spotlight for the presidential race turns to Republicans in South Carolina and Democrats in Nevada on Saturday. Since starting the first-in-the-South primary in 1980, South Carolina Republicans have prided themselves in picking the eventual GOP nominee. But that streak ended in 2012 when Newt Gingrich won the state with 40 percent of the vote to Mitt Romney's 28 percent. South Carolina's polls are open from 7 a.m. to 7 p.m. The caucuses in Nevada began about 11 a.m. local time. Hillary Clinton beat Barack Obama in 2008. But the caucuses have turned out a small number of people, making it tough to predict a winner between Clinton and Bernie Sanders.
