This is what Bernie Sanders said about his decision to not run as a third party candidate in the event he loses the nomination:
“No, I made the promise that I would not and I will keep that promise. And the reason for that is I do not want to be responsible for electing some right-wing Republican to be president of the United States.”
See? And given his track record for honesty and integrity, I think we can depend on Sanders to hold to this promise, because I believe him when he says he doesn’t want to see a Republican in office, especially one of the current ilk.
Can you rightly say you have any reason to believe he would deviate from that promise? If he does, what do you think that would say about him, considering that a substantial part of the reason people love him is BECAUSE of his integrity? He would be breaking his promise, and a particularly big one because it would guarantee a Republican president. If you’re so into politicians being honest, how can you be okay with the idea he might change?
That said, he can virtually be guaranteed to be counted on as not breaking his promise. He isn’t going to run if Clinton gets the nomination. Will you go against his own, very clear, wishes, and vote in a way that gives a Republican the election?
