Political Positions
Ron Paul has been described as conservative, Constitutionalist, and libertarian. His nickname "Dr. No" reflects both his medical degree and his insistence that he will "never vote for legislation unless the proposed measure is expressly authorized by the Constitution."
One scoring method published in the American Journal of Political Science found Paul the most conservative of all 3,320 members of Congress from 1937 to 2002 (wherein "conservative" is defined by a strict reading of the Constitution, rather than its common-usage definition of supporting restrictive, authoritarian, and/or traditional interests). Paul's foreign policy of nonintervention[161] made him the only 2008 Republican presidential candidate to have voted against the Iraq War Resolution in 2002. He advocates withdrawal from the United Nations and the North Atlantic Treaty Organization for reasons of maintaining strong national sovereignty. He supports free trade, rejecting membership in the
North American Free Trade Agreement (NAFTA) and the World Trade Organization as "managed trade". He supports tighter border security and ending welfare benefits for illegal aliens, and opposes birthright citizenship and amnesty;[162] he voted for the Secure Fence Act of 2006. He voted for the Authorization for Use of Military Force Against Terrorists in response to the September 11, 2001, attacks, but suggested war alternatives such as authorizing the president to grant Letters of Marque and Reprisal targeting specific terrorists.
