The Ferguson thing was a big big deal when the 300lb criminal Michael Brown tried to assault a police officer and take his gun. In the aftermath you had an enormous lie spread (eventually debunked by the coroner) that he had his hands up and back turned when shot. Then you had the riots, a US President siding with the criminal against the police and not enforcing law and order.
This really resonated across the state and they sent a message. And good for them.
The funny thing is that the 1992 BILL Clinton wouldn't have made the mistake of buying into Michael Brown's victimstance.
