I think voting for the weaker candidate is a dangerous strategy.
Not only would I be afraid perhaps somehow Bernie would win (although I agree he’s got a smaller chance than Bloomberg to beat Trump), I think the more exposure Bernie gets, the more his radical leftist views deep into the mainstream.
I’m not sure I mind Bloomberg so much, compared to the rest. Not that I like him, but he’s a whole lot more normal than Trump and not nearly as dangerous as some of the other Democrats.
