How is that the House Minority Leader can mix up the U.S. Constitution with the Declaration of Independence in front of a Tea Party crowd at the Capitol? Who knows..but he did it, pulling out his pocket copy of the Constitution he's pledged to uphold, today pledging to "stand here with our Founding Fathers, who wrote in the preamble: 'We hold these truths to be self-evident ..."

Here's more from Rick Sanchez.

SANCHEZ: Representative John Boehner is House minority leader, the number-one Republican in the House of Representatives. So, you would think that he would know the Constitution, know in fact the thing backward and forward.

Well, I got a bit of a surprise for you. Here's John Boehner just a short time ago, House Minority Leader John Boehner addressing a TEA Party rally against health care reform from the marble steps of the U.S. Capitol.

BOEHNER: This is my copy -- this is my copy of the Constitution. And I'm going to stand here with our founding fathers who wrote in the preamble, "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."

SANCHEZ: And do you believe it? As most fifth-graders would know, the document Boehner was quoting is not the Constitution. It's the Declaration of Independence. I'm assuming he knows the difference, but maybe -- I'm not sure now.

Those other House Republicans, the ones behind him, Roy Blunt, Virginia Foxx, Michele Bachmann, are they cringing in despair or just blissfully unaware? I don't know.
