Fourteen states and one U.S. territory are hosting Super Tuesday primary
elections, a flurry that could bring more clarity about which
Democratic presidential contender voters prefer to challenge
Republican President
Donald Trump in November.
More than a third of delegates will be doled out in Tuesday's nominating contests, compared with less than 5% awarded from the four states voting in February.
A candidate needs at least 1,991 delegates to the party's national convention in July to win the Democratic nomination outright.
