The reform package, pushed by DNC Chairman Tom Perez and allies of Vermont Sen. Bernie Sanders, among others, passed overwhelmingly by voice vote at the DNC’s summer meeting here — two years after the process started. Perez and others hailed the outcome as momentous, saying the reforms will help welcome new people into the party by reassuring them that their vote will never be overruled by the party leaders who can vote for whomever they want for the presidential nomination.
