Three cheers for the campaign to oust Debbie Wasserman Schultz as head of the Democratic National Committee: Her efforts to grease every wheel for Hillary Clinton are a disservice to the party, the nation and even to Clinton.

The party chief “is trying to manipulate the presidential election process by limiting direct debate and tilting the national party apparatus in favor of one candidate. This is unacceptable,” says

RootsAction.org co-founder Norman Solomon. As of Friday, the group had 30,000-plus signatures for its ouster effort.

Wasserman Schultz has helped schedule remarkably few debates — six, against the Republicans’ 12. And the timing’s guaranteed to minimize viewership: The Dems’ next debate is on the Sunday in the middle of the Martin Luther King three-day weekend, programmed against the NFL playoffs.

This, notes Jeff Cohen of RootsAction, has led to “domination of the media’s extensive election coverage by the other big party.”

Plus, she moved to deny Bernie Sanders access to his own voter database after some (immediately fired) staffers got caught peeking at others’ data. It took a lawsuit to get Wasserman Schultz to back off.

Clinton would be a stronger general-election candidate for facing a fair primary fight — and Democrats would feel more confidence.

Turning the contest into a coronation isn’t just undemocratic, it’s downright royalist.
