Engaging, Or a Turnoff?
While many found Biden's grins infectious, some found them immature.
"That mugging, those condescending looks — it was a complete turnoff," said body language expert Lillian Glass, author of the upcoming "Body Language Advantage." "He was bullying, he was smug, he interrupted ... I think he lost a lot of his message based on facial gestures."
Biden may have been deemed the winner by many, but "from a body language point of view, he did not win this debate," she said.
