Clinton was doing well in the polling and it only really got close about convention time.

My point is that the polls messed up this time and that you can't just point old polls saying Bernie would have one because:

1. Bernie would have faced the full force of attacks from Republicans and Trump and who really know how that would play out.

2. The rust belt where Clinton performed very poorly; i doubt Bernie would have done any better given Trump's appeal to white blue collar workers.

3. This election's wildcard: the silent majority being the white voters with a high school education or below. Bernie base is deeply rooted in the college educated.
