Kamala’s idiopathic idiocy

Kamala’s idiopathic idiocy: Kamala Harris is deservedly being ridiculed for her evasive responses to questions about her policies, for example: “I was born [raised] in the middle-class.”   Even RFK got in on the act with his audience at a Michigan rally.  Here’s one example of the riff: 

RFK: “And the next time your wife asks you why you didn’t take out the garbage, what are you gonna say?"

Audience:  “I was born in the middle class!”

One can go on and on with this amusement, but it begs the question: What the heck is wrong with her? What is the root of her idiopathic idiocy?
