No wait, do people actually think that quote this merits anger and hostility? Hillary Clinton, and her allies, have been implying this about Bernie Sanders from the very beginning of this year. Hillary Clinton, and her allies, have suggested that Bernie Sanders isn't a real Democrat, that he's "a liar", that he's opposed to the Affordable Care Act, that he was opposed to the auto bailout, that he's responsible for Sandy Hook etc. To me, that's a pretty dirty campaign rooted in deception and spin.
Welcome to the big league. The gloves come off.
Even though Sanders has been in Congress for decades, he is a completely unvetted as a national candidate. Sending a completely unvetted candidate straight into the GOP attack firestorm is a terrible idea. This isn't Hillary's first rodeo.
