We need to clarify something first. I don't believe there was a more qualified candidate to actually legislate, than Hillary.....warts and all. But, she did have warts, and Bernie appealed to the masses who don't necessarily follow the issues, but they loved his (flawed) platform.
I love that he finally came out with my idea for a fee on Wall St. transactions, but he wanted to piss the money away on silly programs that didn't really make sense.
I said the problem was with Independents (read...college kids and much of the Obama coalition) who wanted to teach the DNC a lesson.
I don't know if I agree with your numbers re Bernie supporters. Many voted for trump, and many stayed home. You might be referring to people who voted....but that wasn't what got trump elected.
I view 'qualifications' a bit differently. I view qualifications as being able to do things like fight for the right policies, not have 'experience' governing.
I don't see Bernie's platform as flawed, I see Hillary's as flawed. My numbers are from the polls and studies of voters.
One thing that can be a bit misleading is that some of his support was from independents who were never going to support any other Democrats, so losing them wasn't really a loss.
You sure seem snide about him. He didn't 'finally' come out with 'your' policy, and he was going to use the money for a very good purpose - $50 billion of the $300 billion to pay for free public tuition.
