The Democrat Party’s rules committee Saturday struck a deal between supporters of Hillary Clinton and Sen. Bernie Sanders, agreeing to reduce by about 60 percent the number of “super delegates” who are not bound by voters in the primaries.

Members of Congress, governors and “distinguished party leaders” remain unpledged and can support the nominee of their choice, but all other unpledged superdelegates are “required to cast their vote at the Convention for candidates in proportion to the vote received for each candidate in their state,” according to the Washington Post.
