There is no stinkin’ way this guy EVER even attended a class on constituional law let alone taught it.
That's been obvious from his early days in the White House. What he knows of the Constitution, he learned at the knees of radical Marxist professors who despise the Constitution and our founding.
He knows that stuff like the back of his hand, but can't explain with any authority how our form of government works under its root document. It shows in everything he does.
I viewed an exam of “Professor” Obama when he was “teaching”. One of the exam questions was about the rights of a gay couple in adopting a baby.
Not much about the constitution, all about agitating.
