Bernie Sanders supporters to superdelegates: Stop backing Clinton

Superdelegates, which include Democratic governors and Democratic members of Congress, are automatic delegates to the Democratic National Convention. And they can choose whomever they want to be the Democratic nominee, regardless of which candidate wins their state's primary or caucuses.

In Washington state, where Bernie Sanders won nearly 73 percent of delegates at precinct caucuses in March, most superdelegates are still supporting Clinton. And they're hearing plenty from Bernie supporters about why that's unfair.
