I don't know that all are "Obama Supporters" per se. Some are merely snobs who resent seeing "their" party taken over by the likes of Sarah Palin and Joe the Plumber. In any case, their "purity" is the same as a vote for the Obomunist.
They are Sans-Culotte, all have linkable statements or endorsements, this is not merely “outrage and hate” this is keeping track of who said what, and their rationales for doing so.
