Democratic Party officials voted Saturday to strip superdelegates of much of their power in the presidential nominating process, infuriating many traditionalists while handing a victory to the party’s left flank. The measure’s overwhelming approval – met by cheers in a hotel ballroom here – concluded a tense summer meeting of the Democratic National Committee, which had labored over the issue since 2016. Superdelegates that year largely sided with Hillary Clinton over Bernie Sanders, enraging Sanders’ supporters.
Two years after his defeat in the 2016 presidential primary, the Vermont senator has amassed a growing string of losses in races in which he has intervened. Beginning last year, Sanders-backed candidates faltered in an Omaha mayoral race and a nationally watched House race in Montana.
