@hawkeye10,
I just saw this. Your expanded "explanation" doesn't work. Bernie is very close to people, and hugs and loves all kinds of people. I see evidence of his warmth and people-persona all the time.
Hillary has been avoiding crowds. Even though she could try to throw on a down home persona as she's done before, it comes off as fake and staged. Of course those who are heavily invested in her winning will excuse whatever she does, but Bernie is genuinely a caring man.
But, I don't think he'd win a soundbyte debate. That is HRC's wheelhouse.
