Your implicit claim that had Bernie Sanders won the Democratic nomination things would have been different is difficult if not impossible to substantiate. Putin still would have hacked the election in Trump's favor, legitimate doubt would have been cast on the feasibility of Sanders' economic platform, and other aspects of his past positions as senator would have been brought up. You'd also have to assume that all that toxic racism generated by Trump would have been checked by the hope that Sanders was campaigning on. In retrospect, I'd say the racist instinct would still have won, especially with Putin's role in the election. It would have been interesting to see how Putin would have approached delegitimizing Sanders through wikileaks. Maybe that happened in an alternate universe somewhere and they're writing now about how Sanders blew it. Either way, Putin held the wildcard and his favorite was Trump.
