ANSWER: Dubious Jefferson Quote by U.S.Senator Jim DeMint

answer: 

A good place to check is the University of Virginia's Electronic Text Center page: Thomas Jefferson on Politics and Government. These quoted passages don't show up readily - either in their site search, or in the Table of Contents of the quotes.

The most dedicated researcher may even want to plow through more Jefferson sites, maybe starting with Google's directory, or the Library of Congress American Memory
