Winning Wisconsin, Michigan and Pennsylvanie would have been enough for Hillary to win the election. In these 3 states, Trump won by less than 1%. Don't tell me Bernie wouldn't have won these 3 industrial states...
I really don't think so. Trump was the one with the 'message' that (right or wrong) resonated most there. Yes Sanders beat Clinton in the primaries in 2 of those states, but again in a general election, which is a different kind of ******, the GOP was just loaded with dirt on Sanders, and some of that dirt would have had a lot of influence in those states.
Plus Sanders might have lost a state or two that Clinton won.
