As soon as the debate is available for after event viewing, I would encourage you to find and view it. One thing that stood out to me is how "blinky" Virg Bernero is. (In particular, a 'tic' in his right eye) It made me do a quick search for things that it may represent.  I found this:

How To Tell If Someone Is Lying

• Try changing the topic and see how easily the liar will be ready to change the subject. His body and face will look relaxed.
  
• If you think he is giving false answers to your questions, try asking him minute details. He will take unusual breaks as his brain will take time to imagine and construct a story with minute details.
  
• Try asking minute details after a considerable time gap. Most of the times, the liar will have different answers. This happens because an imaginary story is difficult to remember.
  
• A liar might even try to confuse the listener by adding unnecessary details and deviating from the main issue.
  
• Ask the liar to look into your eyes all the time while talking to you. If you are a good observer, even a slightest change in his eye-movement that is connected with lying will be noticed. It will be useful to warn him to tell only the truth.
  
• One of the easiest ways of catching a liar is to let him speak without asking him any questions. The more explanation you hear from him, the more possibility of him lying.
  

Unfortunately, some of the symptoms require more time, and more 'rope' than what a debate format can offer..

The particular quote that initially drew my attention?

"Too Much of Eye Blinking: Lying has a stressful effect on the liar's body. If a person is lying, his eyes are strained resulting in too much of eye blinking."

Folks, as you know, I have my misgivings, but I will tell you, the times I have met Rick Snyder in person, he looked me in the eye and didn't blink or look away.  I had his full attention for as long as I wanted to talk.  This is only ONE thing to pull away from the debate, and I do encourage you to look. The strobe must have been terrible for ol Virg.
