No one cares what I think, but here goes.
The DNC chair has been held by the dominant of the warring factions of the democrat party for decades. The DNC doesn't even pretend to act in a way to benefit democrats. They are there to benefit their benefactor. The DNC was stacked for Gore, and later Kerry, against Clinton in '08, Clinton secured control to her benefit this time.
The Sanders wing supports keith, the Clinton wing supports Howard. You need to give it to a neutral party. You are probably even in denial that your party is severely fractured. It is far more fractured than you like to pretend Republicans are.
I see O'Malley wants it. He might be a good choice.
