Oh come on, the Jill Stein stuff is nonsense. No one voted for Jill Stein, they voted for "Candidate from left-wing party that isn't Hillary". If you want to say that Sanders' rhetoric pushed people to voting for her, fine. If you want to say that Russian anti-Clinton campaigning hurt her, fine.
But the idea that her connections to Russia specifically helped her is completely absurd. The Green Party would have taken the same vote share if their nominee was a bronze statue of Ralph Nader.
They are REALLY, really, upset over this loss.
They've become irrational over it and it's quite sad. They're reacting worse than how Republicans reacted when Trump beat them.
