This is a great example of one of the key pathologies of liberals. They're playing by the rules, and think that if they play well enough, they will win because the rules say so. They don't understand that we don't have rules, we have a ruling class, and they can make and break the "rules" they set up with complete impunity. Obviously the corporate dems are controlled opposition, they understand, but ideological liberals are convinced that they can outmaneuver power using the rules and laws that power set up and can ignore at will.
