It's much harder for Sanders to win the primary than the general. If he's a talented enough campaigner to snag the nomination away from Hillary, to say he can't beat the Republican nominee is delusional.
Fair enough. That being said, I don't intend to make things easier for him. He's going to need to prove himself before I can even think about supporting him.
I'd rather lose the GE with Bernie Sanders, a candidate who stands for something - rather than losing with the bloodless, deceiving liar and corporate enabler Hillary Clinton.
Sounds an awful lot like cutting off your nose to spite your face. You go do that, meanwhile I'll actually try to win elections.
Winning elections alone does not matter though, if you give up all your principles. It seems you have no self-confidence if you believe that Sanders cannot win an election. People said the same about Obama and then he defeated her and won the GE twice. Obama has one of the strongest charismas in the whole world. Sanders has hardly any charisma whatsoever. Sanders comes across as really angry all of the time and you can bet that turns a lot of people really off. Not just a little, but really, really, really off. Sanders would be really lucky just by winning 35% in a general election. Seriously.
