During his CPAC speech, Rush Limbaugh said conservatives “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, Liberty, Freedom. And the pursuit of happiness.”
Conservatives may believe that, but it just isn't so. The language Limbaugh was referring to actually appears (more or less; he made some changes) in the Declaration of Independence.
