Hillary Clinton acknowledged the historic moment in a speech in Brooklyn, NY: it appears she’ll be the first woman in the nation’s history to be nominated by a major American political party to be president. But Bernie Sanders wasn’t having any of it. He barely mentioned Clinton at his rally in California, spending much more time on Donald Trump. And he stuck with his stump speech staples, healthcare and Wall Street, and vowed to press ahead to the final primary in Washington DC June 8th, and on to Philadelphia for the convention in July. When Sanders did finally mention Clinton, the crowd at the Santa Monica rally booed. What does this portend for the campaign going forward?
