The more post mortems I read, the more obvious the problem with Clinton's campaign becomes. Her refusal to openly welcome Bernie supporters immediately after the primaries cost her the working class vote. Instead of listening to Bill, they just "assumed" that the working class was lost, and never even really tried to appeal to them emotionally. Trump proved that people need to be stirred. The american public responds poorly to being mostly explained to. There needs to be an authentic appeal to emotion there, and even though I believed that Clinton had it, she just blew her best chance to project it.
Hopefully the DNC learns from their mistakes, cans Brazile, and hires on Bernie's recommendation for DNC chair.
edit - and let's be honest: a lot of these Trump supporters were not attentive enough to believe any of the truth about his campaign. Most people just assumed everything from both sides was propaganda and chose based on who would be a "better businessman". I've heard that argument far too much in the past few days.
