On the left, those who feel the Bern demonize Hillary Clinton and the entire Democratic Party but ignore what progressive politics has achieved, starting with Franklin D. Roosevelt and the New Deal. Ms. Clinton has made unnecessarily personal attacks on Mr. Sanders and he on her. Both agree that the endgame is a Democratic victory in November in every race at every level, yet both would leave the other mortally wounded before that contest. Mr. Sanders' vision of an American ecology of honesty, prosperity, education and freedom underwritten by enormous sums collected from the One Percent, Wall Street and Big Business, is a pipe dream as long as the GOP controls Congress and Mr. Sanders does not relinquish his sense of self as an Outsider. Ms. Clinton's personal arrogance has led her nearly to self-destruction.
