Sanders backers have expressed frustration over the nominating procedures, the party platform and party leadership, with some suggesting they may protest or take action on the floor. While party chairwoman Debbie Wasserman Schultz is stepping down soon, she will still have a convention role, which could draw jeers from Sanders delegates. At a committee meeting the previous day, Sanders backers shouted "shame, shame, shame" as amendments to abolish or limit superdelegates in future nominating competitions were voted down. He successfully won major platform concessions, including a $15 federal minimum wage, abolishing the death penalty and breaking up large Wall Street banks. [...] at the DNC rules committee the two sides agreed on a "unity commission" that will review changes to the nominating process, including limiting the role of superdelegates. After the unity commission agreement, Sanders supporters seeking to pass amendments to abolish or curtail superdelegates opted against pursuing convention floor fights on the issue.
