I saw a film clip of the Iowa man "shaking" old newt's hand and blasting him but good. First, newt tried to apologize...then newt tried to "break the grip" of the handshake....all the while the Iowa man was castigating old newt up one side and down the other while maintaining the near death grip on old newt's hand. Near the end, newt was at a loss for words, the Iowa voter dropped the "handshake" and turned his back on old newt.
I would highly suggest we all - at least figuratively - do the same.
