It means they don't actually care about Sanders's platform at all, nor the fact that he's on record saying that people should vote for Clinton if Sanders doesn't win the primary.
It also means they're willing to vote for a stridently anti-science candidate just because they got their feelings hurt.
I get that you want to beat up on how dumb the Berniebros are, but neither of these things would be hypocritical if true and I don't think either of them are true. It's possible to agree with Bernie's ideas but disagree that he's correctly identified the best way to implement them in the absence of his victory; it's also possible to believe that your vote, even if it has no chance of being cast for the winner, expresses an important principle.
Finally, while Stein's anti-GMO position is nutso, the world isn't reddit and a lot of people weigh other issues above GMOs on the scale of political importance. Even among Greens, I can't imagine GMOs make the top 10 or 20 issues versus foreign policy pacifism, education, pensions, access to healthcare, poverty reduction, a carbon tax, supporting union labour, etc.
It would plainly be inappropriate for someone to tell you you're voting for a strident murderer and war hawk simply because you've chosen to support Hillary, because a) that's reductionist, and b) people would be imputing motives to you that aren't fair.
It's OK for people to vote for who they want to vote for. The only thing more embarrassing that losers flailing around because they can't cope with losing is winners flailing around because they can't cope with
winning.
I never said wait until July, or at least I did not intend to. Yes, I alluded to fluid super delegate votes, but I don't even care about them, as I've also said. Pledged count. Lock up the pledged count -- which will happen as soon as the polls close tomorrow -- and make the call. Without a concession from Sanders (or any other candidate in the same position), it's the proper thing to do in my opinion.
I mean, this also seems a little weird, because if you want to allow for the practical impossibility of Bernie winning the pledged delegates based on his performance tomorrow (he'd need to beat his best-state performances in primaries and caucuses), then why not also allow for the practical impossibility of Bernie flipping all the superdelegates across the board?
