California Gov. Jerry Brown (D) compared Trump supporters to Neanderthal-era cave-dwellers at a global warming speech in New York City.
He said the "derivation" of the term "Trump-ite" is similar to that of "troglodyte," which is the scientific term for cavemen.
"You should check out the derivation of Trump-ite and troglodyte, because they both refer to people who dwell in deep dark caves," he said, according to Politico.
The left according to Rush use this issue as the reason why the government must control every aspect of our lives and thwart individualism and liberty.
