Re: The 112th Congress: Debt ceiling edition
I don't think the primaries are "rigged," and I don't think they've produced extreme nominees. The party system will definitely give us nominees who pass broad party litmus tests and there are pros and cons with that. I can't imagine an independent president ever getting anything difficult accomplished, for example, since he would have no base within Congress to appeal to.
Insofar as there is a magic bullet, it's campaign finance reform. We'll never take bribery out of the system entirely, but right now the system actively encourages it.
One thing that always comes up as a solution is term limits, and I am here to tell you that is a terrible, terrible idea. In politics, process expertise is a vital source of power, and neophyte members and staffers cannot compete with the permanent presence of lobbyists in DC. Term limits will simply give the moneyed interests that much more power.
Use all the democratic institutional and cultural methods available: vote, proselytize, organize, GOTV. If all else fails, there's always peaceful civil disobedience.
