Bernie used dog-whistles in trying to appeal broadly to as many people as possible with the generalities of his unusual platform much as, another violent racist, Ron Paul had, while Hillary was truly authentic and familiar with the minority experience and spoke to it from the heart.
Like how she was being investigated for federal crimes, black people could identify with that. Bernie had nothing. And Hillary had her beard marriage with Bill while having a lesbian relationship on the side with Huma, extremist lesbian TERFs could identify with that. Bernie had nothing. And when Hillary died on 9/11, all of America could identify with that. Bernie had nothing.
