"[Some of my opponents] do not want to change the Constitution, but I believe it's a lot easier to change the Constitution than it would be to change the word of the living God, and that's what we need to do is to amend the Constitution so it's in God's standards rather than try to change God's standards."
First, note that it is not necessary to change either the Constitution *or* "God's standards"...under our Constitution individuals are free to conform their lives to what they think God's standards are, however they define God, as long as their behavior does not prevent someone else from following a different understanding of God's standards.
Second, note that anyone elected President will swear, at his/her inauguration, to uphold and defend the Constitution of the United States. Anyone who cannot so swear will, if honorable, not seek election to that or any other public office where such an oath of office is administered. Anyone who continues to run for an office where he must swear to uphold and defend the Constitution--knowing that he intends to dismantle and transform it into a religious document--cannot be considered honorable. More than that, such blatant disregard for the Constitution is unAmerican and unpatriotic.
Third, note that this is Mr. Huckabee's own words...not what someone says he thinks, but what he himself chose to say.
Fourth, changing the Constitution to fit with one religion's view of "God's standards" is, in fact, creating a theocracy from a secular government. It is no different than Islamic countries being ruled by Sharia law: it is a government founded on theology, on a particular and exclusive concept of what God wants.
Imagine if every politician of another religion said that sort of thing...what if, for instance, John F. Kennedy had said we needed to change the Constitution to accord with Roman Catholic ideas of "God's standards."
We've had enough of Presidents (and Vice presidents, for that matter) with no respect for the Constitution, who broke their oaths of office. We don't need this one.
