For the BILLIONTH time....let's say everything was fair and equal and no rigging took place in the 2016 primary for argument's sake:

Bernie as an outsider almost took HALF of Hillary's party. If Hillary split her own party's votes then why project her unfavorability to the general election to appeal to people who were DECIDEDLY not Democrats? Bernie would have kept his base PLUS Hillary's crowd PLUS Independents (his base that wasn't even allowed in the primaries) PLUS Republicans that didn't want to vote for Trump PLUS the millions of first year voters who registered to vote for HIM.

To add in a sprinkling of it being fixed, the entire process was set up to steer Hillary to the nomination AND presidency - including Trumps elevation to be opposite her. The better question is if Hillary barely beat Bernie why would she do better in a situation she didn't control against the general electorate? People protested her nomination at her own nomination! Haha the writing was on the wall. Bernie would have won.
