The Democratic establishment and their political consultants are pretty much the same exact group. It's a revolving door system to distribute campaign donations. DNC members move in and out of the various campaign organizations, consultancies, and government positions.

Campaign money gets spent on consultants who take a cut and spend most of the rest on ineffective television adds. The primary purpose of the adds is not to reach voters, but to purchase the loyalty of broadcasters who will then cooperate with campaigns. That's why they have been so slow to shift to the Internet, even though it provides the most bang for the buck. Leverage over broadcasters is crucial in maintaining a news blackout for progressive candidates.
