It would not have been as likely if they had nominated Sanders and tried to enact reforms to go into the direction of European social democratic countries.

I'm pretty sure that would pacify wide swaths of the country, not that I'd like that, but if they were actually interested in not having the country go to a fascist they would've done something like that.
But the capital interests behind them and through their decade long self-indoctrination they can't even accept a bit of reformism if it could potentially cut into profits.
