I worked with the retarded for a couple years shortly after high school. What we refered to as “High Functioning” then was in the 40-50 range.
I remember several of the ‘clients’ being far more intelligent than I have seen in speeches by congress/senators. And that’s not a stretch. They spoke better, carried themselves better and displayed far more coherent ideas/concepts/understanding.
What we elected are in large part functioning morons that someone gave the Pavlov treatment, cleaned up and instruct to bark the proper tune on command. They probably do not possess an original thought that does not include TV listings, Ice cream or making their handler smile at them.
And if they do, I do not believe there is verifiable evidence available documenting an instance of it happening.
