DNC chair Debbie Wasserman Schultz needs to be removed. He or she does not have to be progressive but they need to wake up every morning looking to grow the party. They need to be able to go head to head with Nancy and Harry without worrying about committee assignments. If needed they need to withhold money from candidates who stray. They need to instill core principles that candidates must echo. Ideological purity isn't needed but the Party has to stand for something.
They certainly need to go to 1600 Pennsylvania Avenue and say Mr. President Labor is serious about withholding support for the DNC. Environmental groups are sure to follow. The DNC is toast if TPP passes. Hillary will likely overcome a weak DNC and the Senate might still change hands but it will be in spite of the DNC not as result of it.
