Hillary Clinton is sinking like a stone. She's falling in the polls. Conversations with her longtime friends and admirers indicate grave worry. She is not generating the excitement that the first prospective woman president should; the email mess is not going away; even the money advantage is not what was anticipated. And a self-declared socialist could defeat her in Iowa and New Hampshire. Even as she tacks left to excite the base, there is no way she can out-Sanders Sanders. If she could just vault over the rest of the pack and claim the nomination, as she hoped when she declared her candidacy, Hillary Clinton might still be a strong nominee. But that's not going to happen.
