While I believe Debbie Wassermann-Schultz has done a fine job in running the Democratic National Committee, i believe in the wake of a contested primary season Someone will need to fall on their sword. For the benefit of party unity and a successful general election she should step down and look for replacement.
The DNC should find a new leader because Debbie Wasserman Schultz has proven herself to be completely inept and in over her head. The days of straight talking points and defending the indefensible are over. She has lost sight of what the party really is, or isn't. Time for a change.
There are rumblings within the Democratic Party that it's time for their National Convention leader, Debbie Wasserman Schultz, to step down. I don't think that's a wise opinion. The Party is already so fractured: between Bernie Sanders' outspoken followers and Hillary Clinton's counterattacks, electing a new DNC leader would just lead to more instability for the Democrats.
Whether or not the DNC should find a new leader is something only the DNC can answer. If they are satisfied with the job the current leader is doing, then she does not need to be replaced. If they come to a point where they are no longer satisfied with the job she is doing, then they should begin to look elsewhere for leadership.
