Not with Trump as her opponent.
And, I say that as someone whose pretty far out in the left side of the political field - it's not that I
like Clinton, (because I really, really don't) but when faced with the choice between a corrupt, pro-establishment neo-liberal insider or an ignorant, bigoted juvenile fascist wanna-be con-artist?
That's not a choice, it's a moral imperative (it's also a damning condemnation of our "democracy", the GOP, and our entire electoral system, but that is beside the point); Trump has already damaged the US, and he's exposed more weaknesses that are unlikely to go unexploited in the future (I suspect it's going to take a while to become obvious, but he's badly warped politics with his open calls for violence and even more overt embrace of ignorance, hate and school-yard "tactics") but what he'd do as President would be far, far worse (oh, people can come up with some imaginary Trump who wouldn't be all bad - that there are voters trying so hard to do exactly that is a testament to how bad things have gotten in the US - but Trump has shown
none of the positive qualities people pretend to assign him; the Trump we see is all we're ever going to get).
