Michigan Top Prize as Six States Hold Democratic Nominating Contests VOA News Voters in six U.S. states cast ballots Tuesday in the race for who will be the Democratic Party's presidential nominee. The focus will be on the key Midwestern state of Michigan, where polls show former Vice President Joe Biden leading Vermont Senator Bernie Sanders. Michigan is the biggest prize in Tuesday's voting with 125 delegates at stake. Sanders won Michigan's 2016 primary, but numerous polls in recent days show him trailing Biden by a double-digit margin. Elections are also being held in Washington, Missouri, Mississippi, Idaho and North Dakota. The contests are the first since last week's Super Tuesday batch of states when the selection process transformed from smaller states holding votes one at a time to multiple states spread across the country voting at the same time. Sanders won California, the biggest state, but it was Biden who emerged as the front-runner by winning 10 of the 14 states last week. .
