As many as 20% of Americans suffer from authoritarian personality disorder. The fact that Wisconsin Governor Walker is desperate to strip the rights and protections from the workers under his control dove tails with his unquestioning obedience of Koch who is clearly his master.

The similarity to the Third Reich is not a coincidence. Once these people have that much power that is exactly how they will behave. It's in their nature, they crave it.
