funny, I think the opposite when i think of Hillary and Sanders. Hillary is the centrist candidate and is one of the few candidates that has the ability to reach across the isle both due to perception and actual experience. She isn't the best candidate, but compared to the extremists (on the American political spectrum) of Trump and Sanders, she is the better choice, and imo the likely winner.
Sanders would essentially be a dead presidency, as congress would shut down any and all of his domestic initiatives. I mean just look at Obama, and people expect Sanders to do better? His views would literally require a sea change in congressional politics and people, and I haven't heard him provide any support or even just point to any new senators or congressmen who would support his ideas. He basically isn't planning the change that Washington would actually need to get his plans passed. Change in Washington doesn't come with a president, it comes with Congress (which makes me laugh when presidential candidates say they will change Washington and people believe them) The President isn't a dictator, he can't rule by fiat. I'm not even sure if Sanders has a roadmap in place beyond the talk.
I'm not even going to bother with Trump, both Sanders and Trump are demagogues as far as I can see. Hillary lacks the charm that Bill Clinton had, but still she is the best candidate for president of those 3.
