Thomas Jefferson warned us of Heretics [RINOs] 1803 AD

"I have spoken of the [Republicans] as if they were a homogenous body, but this is not the truth. Under that name lurks the heretical sect of [liberals]. Afraid to wear their own name, they creep under the mantle of Federalism, and the [Republicans], like sheep permit the fox to take shelter among them, when pursued by dogs. These men have no right to office. If a [liberal] be in office, anywhere, and it be known to the President, the oath he has taken to support the Constitution imperiously requires the instantaneous dismission of such a officer; and I hold the President criminal if he permitted such to remain. To appoint a [liberal] to conduct the affairs of a republic, is like appointing an atheist to the priesthood."

Note: I replaced the word federalist with Republican, and the word monarchist with liberal; but the message is the same.
