Well, I am still giving Bernie the benefit of the doubt even as a Trump supporter. He was my 2nd choice and say had it came down to Cruz vs. Sanders, Sanders would have gotten my vote.
I can't imagine anyone that is rational wouldn't realize the danger of getting in the way of the Clintons, especially Hillary, when it comes money and/or power. I was truly concerned for Sanders and felt some relief when he left the race knowing that he should avoid the "accident" or "suicide by proxy" scenario like others who got in the way of the Clintons.
I wondered if he bought the house as an indication, without using words, that he was paid off.
Many of us gained our familiarity of the Clintons over a span of a couple of decades and know what they are capable of. I mean, imagine being in a spot where you were told to back off or else you and/or your family were at risk.
So, I'm blaming the "Medusa" Clinton for turning Bernie to stone! He looked so defeated at the convention when sitting in the audience.
