The fact that Hillary Clinton has been running in an open election as if she were the incumbent is fairly unprecedented in modern politics. Considering her history, it's astonishing that no one has primaried the former first lady. Many Democrats probably feel as if there's no other viable choice. But despite the generous treatment she's received from the media, Hillary has never been an especially electrifying or potent political power, writes David Harsanyi. And she has never effectively rallied grass-roots activists to her cause—probably because her only real cause is Hillary.
