Democratic front-runner Hillary Clinton wins the Mississippi primary over rival Bernie Sanders and tells voters ''I will work my heart out for you.'' Rough Cut (no reporter narration).
ROUGH CUT (NO REPORTER NARRATION) Democratic front-runner Hillary Clinton won the Mississippi primary over rival Bernie Sanders, CNN projected, as four states voted on Tuesday in presidential nominating contests in both parties. Clinton appeared headed to an easy win in Mississippi, where the electorate is dominated by the African-American voters who have overwhelmingly favored her over Sanders. There were no immediate projections or results for either party in Michigan, the night's biggest prize, where Republican front-runner Donald Trump was hoping to restore some momentum for his campaign after a barrage of attacks from establishment Republicans and a tightening race gave new life to those seeking to block him.
