Early voting helps draw record turnout for Nevada caucuses

More than 70,000 people went to the polls this week in early voting for the Nevada caucuses, nearly eclipsing the total number of voters in the state's 2016 caucuses. The surge comes as many voters focused on the issue of health care, which may have benefited Sen. Bernie Sanders. Nevada Public Radio's Joe Schoenmann joins Hari Sreenivasan with more.
