Does Obama know the difference between the Constitution and the Declaration of Independence?

Modern Conservative reported, via Free Republic:

In last night's State of the Union Address, President Obama said:

We find unity in our incredible diversity, drawing on the promise enshrined in our Constitution: the notion that we are all created equal....

Um, wrong founding document, Mr. President. It is in our Declaration of Independence that we read:

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.

Remember when we were force-fed by many in the media articles about the storied legal career of Barack Obama? The first black President of Harvard Law Review (who never wrote a signed legal opinion; nor released his transcripts) and the teacher of Constitutional Law at the University of Chicago. He was our last best hope to restore respect for the Constitution in the Oval Office.

If George Bush or any Republican had made the same mistake can you imagine the media firestorm? I still recall that the New York Times ran a series of photos on the front-page when George Bush tried to open the wrong door while he was on a diplomatic visit to China. This is leagues above that simple faux pas.

I recall a New York Times article portrayed Obama's years as a constitutional teacher at the University of Chicago Law School  that may relate to his problems understanding the basic principles of our founding documents.

The article noted he avoided legal discussions with fellow teachers:

The Chicago law faculty is full of intellectually fiery friendships that burn across ideological lines. Three times a week, professors do combat over lunch at a special round table in the university's faculty club, and they share and defend their research in workshop discussions. Mr. Obama rarely attended, even when

Now maybe we know why. He just has no idea how the Constitution works. And a President pledges to the best of his ability "to preserve, protect and defend the Constitution of the United States." Of course, he also misread the Supreme Court decision on campaign speech. He has a long history of misunderstanding basic principles of law. In years past, he has complained that the Constitution has been a roadblock to vast change in America.

Maybe someone can give him a copy of this book because he clearly does not understand what he is promised to defend, preserve and protect.
