No; they aren’t. Bernie is a good candidate, Hillary is a bloody awful candidate.
The only thing that could justify voting for Hillary would be if the opposition were led by a fascist or a theocrat…which it almost certainly will be.
Which just makes it doubly important to ensure that Hillary Clinton does not become the Democratic candidate.
If it’s Hillary vs Trump or Hillary vs Cruz, we’re all screwed no matter who wins. The only choice in that election will be “do you want to die in an instantaneous fireball, or would you prefer a slow, lingering but equally fatal sort of thing?”.
