We hold these truths to be self-evident. We just don't know where they are.

When he gave his address to the Conservative Political Action Conference (CPAC) last spring, Rush Limbaugh confused the Constitution with the Declaration of Independence. Said Mr. Limbaugh:

"We want every American to be the best he or she chooses to be. We recognize that we are all individuals. We love and revere our founding documents, the Constitution and the Declaration of Independence. [Applause] We believe that the preamble to the Constitution contains an inarguable truth that we are all endowed by our creator with certain inalienable rights, among them life. [Applause] Liberty, Freedom. [Applause] And the pursuit of happiness. [Applause]"

Keith Olbermann's reaction was predictable; he mocked Limbaugh for the error (fast forward ahead to around 5:50).

My reaction was also predictable. Don't jump on him too hard, liberals, because in no time at all someone on your side of the political spectrum will make the same boo-boo.

Well thanks to the NewsBusters website, I see that the other day it happened. And here's the funny thing: it happened to the exact left wing counterpart to Limbaugh--a chubby, radio talk show host. Furthermore, the error involved the exact same phrase of the Declaration of Independence. And if that's not enough, the guy making the snafu works for the exact same outfit as Olbermann, who reveled in Limbaugh's gaffe:

"Looks like it might be time for summer school instruction in American history for left-wing radio and MSNBC host Ed Schultz.

Here's what a caller said on Schultz's radio show July 16 and Schultz's oblivious response--

CALLER: This gentleman who called previously, asking where in the Constitution does it say that health care should be provided? And I know where it says. It says that you have the right to life, liberty and the pursuit of happiness. So, without health care, people can be deprived of life due to death from lack of medical care.

SCHULTZ: It's true.

CALLER: So, I think it says it right there, you have the right to life, liberty and the pursuit of happiness. It's in the Constitution."

Also predictably, just as Olbermann mocked Limbaugh, NewsBusters blogger Jack Coleman poked fun of Ed Schultz for the error.

Okay, people on the left. Hear me out, folks on the right. Do yourself a favor and quit sneering anytime anyone on the other side gets the Constitution and the Declaration of Independence mixed up. There are a good number of educated folks who have engaged in this foul-up. Give them a break; nobody is perfect.

Besides, we all know the phrase "life, liberty, and the pursuit of happiness" comes from the Gettysburg Address.

Addendum: Oh, my goodness. Would you believe that just five minutes ago from the time I'm writing this, Glen Beck, appearing on "The O'Reilly Factor" did it too? The same mistake, the bit about "life, liberty, and the pursuit of happiness" appearing in the Constitution. No, Bill didn't correct him.

Countdown to someone on the left mocking Beck for the error: five... four... three... And countdown to someone on the left making the same error: five... four... three...
