The crooked Clinton’s are not necessarily stupid, but the excessive lust for money and power gets in the way of rational and reasoned and deliberate thinking.
Bill isn't, but Hillary is. She's a moron, and always has been.
She is an excellent example of something called the Dunning–Kruger effect, which is well explained in a Wikipedia article. Here's a quote:
The Dunning–Kruger effect is a cognitive bias in which relatively unskilled individuals suffer from illusory superiority, mistakenly assessing their ability to be much higher than it really is.Dunning and Kruger attributed this bias to a metacognitive inability of the unskilled to recognize their own ineptitude and evaluate their own ability accurately.
I am indebted to FReeper coloradan for cluing me in to this concept, which is so relevant to todays world and the many moronic bozos who occupy the attention of the public.
