That's not so. It is a duty of an educated citizen to be a passable scholar of the Constitution. Those professionals who claim some unquestionable expertise are most often found to have radical misconceptions of what the Founders meant. The Founders wee good men, they were educated men, they would I am certain have despised the the whole concept of an unquestionable expert on the Constitution where that expert claimed to know or understand things an otherwise educated man could not.
If it wasn't straight forward then the Constitution would be useless. It is clearly understandable. The left and their "scholars" try to obscure it as they destroy it.
