Why would you want to vote against Hillary?
Look at it this way - the vast majority of Bernie supporters are young people. If (when) he’s not their candidate, they’re either going to be dis-spirited and stay home and dream of their commie utopia, or vote for the REAL outsider in the race - Trump.
In other words, I think Trump has a better chance of winning if Hillary is the candidate (and, at this point, that looks like a done deal anyway).
I will vote against her in the primaries and against her again in the generals, if it comes to that.
It's a shame that I have to vote for a Socialist. The Democratic primaries are rigged in Hillary's favor, by superdelegates.
Hillary is the bigger threat. No one, including Sanders himself, thinks he can win in the general election.
She also has the backing of the big money and big media.
Low-information voters can be manipulated into supporting Hillary in the general. I don't think they are as easily fooled by Sanders.
