In Chicago, Democratic Party officials voted Saturday to vastly reduce the power of superdelegates in choosing the party’s presidential nominee. The new rules, voted on at the Democratic National Committee’s summer meeting, will prohibit superdelegates from voting on the first ballot of the presidential nominating process at the party’s convention. The change comes after the highly contentious role of superdelegates during the 2016 Democratic primary between former Secretary of State Hillary Clinton and Vermont Senator Bernie Sanders. We’ll have more on the Democratic Party and superdelegates later in the broadcast.
