Honestly, the Democrats can't come after the Greens (or anybody else) and say that we're wrong for supporting a losing candidate based upon ideology
when they do the same thing. They
knew that Hillary was unpopular, and it would have been pragmatic and sensible to abandon her, but they wouldn't do it.
Probably my favorite story about the 2016 election was
one of the DNC emails exposed by WikiLeaks.
It seems that Hillary was such a bad candidate, she couldn't even win when she got to pick her opponent.
