Sanders began the campaign with decency and dignity. Who can forget the first debate with Hillary Clinton, when he said that voters are sick of hearing about her "damn emails" and that he just wanted to talk about the issues? It was a graceful moment, perhaps the best of his campaign. It's simply sad to see this gentleman, dragged down by an old man's ambition and the seduction of the crowd, stooping to personal attacks and an ugliness that threatens more than just his legacy.
