the idea, currently bruited by palin and hinted at by many others, that obama should be impeached for things like granting waivers to the aca, is just ridiculous. but i say again that nothing in the history of the republic has been as impeachable as nsa. the extreme abuse of power, the global violation of the constitution, the performance of billions of acts that would be criminal if not done by officials: those are the sort of abuses of citizens that impeachment was designed to redress. if not, as jefferson said, insurrection is the only possibility. that's going to be hard when they have all our communications, however.
