My Republican “representative” voted for every single version of the bank bailout, including the original “blank check and to hell with balance” proposal, despite a torrent of calls to his office from his constituents asking him not to. (I called him 3 times myself.)
As for being a principled libertarian, I’m sorry (and very sympathetic; I voted Green!) but Libertarianism has been stigmatized by its lunatic fringe, and your opposition is going to work to maintain that stigma. Gary Johnson’s blundering didn’t help any, either.
