BLUE ON BLUE: House Dems seethe over superdelegates plan.

But the members’ angst may not help them since it appears that the DNC is ready to rein in the status of superdelegates, also known as “unpledged” delegates, no matter what lawmakers say or do.

Superdelegates include members of Congress, governors, party elders such as former presidents and vice presidents, DNC members and other assorted “distinguished party leaders.” They made up roughly 15 percent of the delegates during the 2016 convention. Unlike other delegates, they are free to vote for any candidate they want.

The logic is that party leaders immersed in the candidates and issues of the day can provide a guardrail against selecting an “unelectable” nominee for the general election. But the party base loathes this elite class of delegates, saying it stacks the primary process against the wishes of regular voters.

This development was probably inevitable once Tom Perez and Keith Ellison got control of the DNC. In any case, they’re clearing the deck for Bernie Sanders, Kamala Harris, or some other hard-progressive candidate.
