They would blink, cough, and go back to what they were doing, knowing that there is no penalty for violating the Constitution (one of Patrick Henry's chief complaints about the document).

The only penalty is not being re-elected. The problem we've had for the longest time is an uneducated/complacent/apathetic voter.
Idea for a billboard:
"Unemployed? Depressed? Angry?
Don't Beat Your Wife...
Beat A Democrat..."
