This is the quintessential "Joe" moment!
Being faced with a video camera and not having a squad of paid handlers there to control the situation is Joe's nightmare. Spazeboy took the initiative and had his question loaded and ready to fire when the moment was right.
“Would you unequivocally caucus with the Democrats?”
Watching Joe scurrying like a crab down the stairs, trying to escape the harsh glare of reality, I almost expected him to pull his coat over his head like a Mafia "don" leaving court after a hearing. Surreal.
