You are laying the blame in the wrong place. You should be mad at the Clinton campaign, they fucked this up so bad its not even funny. She lost Pennsylvania where she put a lot of effort in the final days. She lost Wisconsin because she didn't visit once since her primary win. She had to many rallies with "A listers" and assumed because people were excited about X person, they were excited about her. Even without the Green Party she would have lost in states she was expected to win.
Not to mention the shitty Primary system that democrats have, they have made it un-democratic. I really believe Sanders could have run away with this. He had the energy and enthusiasm from his base that could have matched Trumps. Instead because of this stupid system from day one she had all these votes for her that shouldn't be announced until much later in the primaries. People jumped on the bandwagon and basically fucked themselves out of the White House.
You have no one to legitimately blame but your own party.
