Did Obama purposefully misquote the Declaration of Independence?

Given the ruckus about Obama and religion, one would think that he would be more careful about these things or that at the very least the WH would quickly say he misspoke. Why he does these things isn't obvious unless he and his aides think that this will let them paint the opposition as kooks. But, with weeks to go before the election, I have a hard time believing that is really what is happening. This is how it should 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.
