Ted Cruz knows more about the law and our Constitution than you will EVER learn in your life time, so please give it a rest.
That is just speculation. You have no knowledge of what Cruz does or does not know about the Constitution.
Furthermore, dedicated Scholars of Constitutional law do not go to great lengths studying that aspect of article II. The rest of the constitution is far more significant in regards to most law and issues in this nation. The vast bulk of study has been on the greater body of the constitution, and not on that one small part of it that has never been needed until 2008.
Regarding Article II, Most Constitutional law people simply accept the stuff everyone parrots in their ear. It simply has never been a significant area of study for them.
