Ist off, no true Dem voted for Trump, and 2nd, those that wasted their vote for Stein were assholes.
Point being, I think a lot of Sanders supporters sat on their hands instead of voting for Clinton, or am I wrong?
Those few thousands cost Clinton the election, like in Pennsylvania, which gave him the Electoral College win
These are the stats for Pennsylvania, which Clinton lost by 44,292 votes
Donald J. Trump Republican 2,970,733
Hillary Clinton Democrat 2,926,441
Gary Johnson Libertarian 146,715
Others Independent 51,306
Jill Stein Green 49,941
So, if the Greens/Independants had pulled their heads out of their asses, Trump wouldn't be POTUS.
