Leave it to Tekla to win the thread again.
But if these close to 2 million people did "get up" and just involve themselves in the primary process, they could purge a few of the members of Congress who are responsible for gridlock and elect a "Gang of X" who could get government doing things again. But if they tried anything after that, they're just playing spoiler and undermining their own interests.
BTW, I don't trust any group that won't state their goals or policy positions. Its like "vote for us, but don't mind what we'll do once in power."
