The resignation of Debbie Wasserman Schultz as head of the DNC will be enough to produce changes. She was seen as too close to Hillary Clinton, and her e-mails were embarrassing. As head of the organization, she has to take responsibility. A new leader will produce a better image that will flow down.
The DNC does need a different direction and there are many ways to implement the change. One method is a change of people and other methods are a change of policy or platform. The DNC needs to adapt to new goals and the best way to change the leadership in Congress.
The Democrats have a problem in that both their main candidate and now Ms. Schultz have problems with the security of electronic communications. That issue has been brushed off as if that type of security breach does not matter. As if that is not enough, the substance of the recent e-mail leaks reveals fundamental unfairness in a party that claims to value fairness and equality. Mr. Sanders' supporters are rightfully outraged, and the DNC should take some type of disciplinary action against those responsible for the mistreatment of Mr. Sanders.
I do not think the resignation of Debbie Wasserman Schultz is enough to take the DNC in a different direction. The DNC is more than one person. Even as chairman, Schultz was not solely responsible for leaked emails and other grave errors made by the DNC. Her resignation will likely serve as little more than a symbol, but I don't believe it will take the DNC in a different direction.
