Here is what Limbaugh said:
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.
Jefferson didn’t include “freedom” in the list because it is considered synonymous to “liberty.”
This is the kind of stupid mistake that Limbaugh would endlessly mock on his radio show if it was made by a liberal politician.
