"Will a Mormon president treat constitutional clauses as divine injunctions?"

"If so, what grounds will we non-Mormons have for interpreting with secular arguments what is presented as God’s will? For that matter, what right will the Supreme Court have to treat the document as anything less than a divinely inspired covenant? Does the First Amendment actually separate church and state, or does that not count, since it is merely an amendment, not the original word of God? But why, then, did a mere amendment change the first inspiration that made slaves less than full persons?"

Garry Wills, he's not anti-Mormon. He just has questions. A lot of questions. Can't blame a man for asking questions, can you? I'd say you can. This is an effort to smear Romney with some really silly insinuations. Why would the fact that the President is a Mormon — even assuming Wills states the belief correctly and Romney himself holds that belief — affect what the Constitution means, what non-Mormons will be able to think about what it means, and how the Supreme Court would interpret it?

In any case, isn't the belief that the framers of the Constitution were divinely inspired fairly common? Where does it get you... other than to profound reverence and dedication? What's wrong with that? The President is supposed to be dedicated to the Constitution. The original Constitution is structured around the existing institution of slavery, but what's the point of bringing that up? Wills is asking questions, not making arguments, which let's him be very slippery. He knows that the part of the Constitution that liberals care about is all in the amendments, and perhaps he'd like to separate the good part of the Constitution — the amendments — from the bad part — the part with slavery... and all the structural safeguards that conservatives would like to see enforced.
