Less than three months before Democrats cast their first primary votes, none of the party’s presidential candidates is polling regularly above 30 percent. Some in the party worry that could hamper its ability to defeat Trump, although others argue that a tough primary will strengthen the eventual nominee. That’s the qualifying level for earning delegates to the Democratic convention, and it is imposed at both the statewide and congressional district level. ADThe last significant three-way delegate contest in the Democratic Party took place in 1984, when the Rev. Mondale won the nomination at the convention largely by grabbing the support of a majority of superdelegates — party leaders and dignitaries who have voting rights at the convention.
