Challenge Trump to take an IQ test: "Prove you're not a complete idiot"

Donald Trump has repeatedly attacked opponents as "low IQ" individuals -- several of whom have now challenged him to "show me yours and I'll show you mine."  But he won't do it.

Why won't he take an IQ test himself? Why won't he prove he's not a complete idiot, as appears to be the case, more and more each day?

Add your name, and challenge him to do it: "President Trump, take an IQ test yourself, and let the world see how you compare to those you attacked as 'low IQ."
