"Early opposition in the postwar era was relatively mild and consisted in large part of various campaigns to repeal the 16th Amendment. Of these, the most important were attempts to pass the so-called "Liberty Amendment." First introduced in Congress in 1952, it essentially tried to strengthen states' rights. However, in 1957 Congressman Elmer Hoffman of Illinois introduced a revised version of the Liberty Amendment that included a section mandating the abolition of income, estate and gift taxes. In this form, the amendment garnered considerable support among extreme right-wing conservatives as well as the budding libertarian movement.
In the late 1950s, Willis Stone became national chairman of the Liberty Amendment Committee and tried to raise support for the proposed amendment through a book, Action for Americans. Stone and the Committee were able to persuade several state legislatures (eventually nine) to request that Congress send the amendment to the states for ratification, but this fell far short of the requirements for a constitutional amendment. Since then, far-right conservatives have repeatedly tried to reintroduce the Liberty Amendment in Congress -- most recently by Congressman Ron Paul of Texas in 1998 -- but without any success. Given the costs of the Cold War and the simultaneous expansion of government services in the 1950s and 1960s, it is not surprising that Stone and the Liberty Amendment Committee had little chance of success.
