Ronald Ernest Paul (born August 20, 1935) is an American author, physician and retired politician who served as the U.S. Representative for Texas's 22nd congressional district from 1976 to 1977 and again from 1979 to 1985, and for Texas's 14th congressional district from 1997 to 2013. On three occasions, he sought the presidency of the United States: as the Libertarian Party nominee in 1988 and as a candidate in the Republican primaries of 2008 and 2012. Paul is a critic of the federal government's fiscal policies, especially the existence of the Federal Reserve and the tax policy, as well as the military-industrial complex, and the War on Drugs. He has also been a vocal critic of mass surveillance policies such as the USA PATRIOT Act and the NSA surveillance programs.

Paul served in Congress three different periods: first from 1976 to 1977, after he won a special election, then from 1979 to 1985, and finally from 1997 to 2013.  In his early years, Paul served on the House Banking Committee, where he blamed the Federal Reserve for inflation and spoke against the banking mismanagement that resulted in the savings and loan crisis. Paul argued for a return to the gold standard maintained by the US from 1873-1933, and with Senator Jesse Helms convinced the Congress to study the issue. He spoke against the reinstatement of registration for the military draft in 1980, in opposition to President Jimmy Carter and the majority of his fellow Republican members of Congress.  During his first term, Paul founded the Foundation for Rational Economics and Education (FREE), a non-profit think tank dedicated to promoting principles of limited government and free-market economics. In 1984, Paul became the first chairman of the Citizens for a Sound Economy (CSE), a conservative political group founded by Charles and David Koch "to fight for less government, lower taxes, and less regulation." CSE started a Tea Party protest against high taxes in 2002. In 2004, Citizens for a Sound Economy split into two new organizations, with Citizens for a Sound Economy being renamed as FreedomWorks, and Citizens for a Sound Economy Foundation becoming Americans for Prosperity. The two organizations would become key players in the Tea Party movement from 2009 onward.  Paul proposed term-limit legislation multiple times, while himself serving four terms in the House of Representatives. In 1984, he decided to retire from the House in order to run for the U.S. Senate, complaining in his House farewell address that "Special interests have replaced the concern that the Founders had for general welfare... It's difficult for one who loves true liberty and utterly detests the power of the state to come to Washington for a period of time and not leave a true cynic." Paul lost the Republican primary to Phil Gramm, who had switched parties the previous year from Democrat to Republican. Another candidate of the senatorial primary was Henry Grover, a conservative former state legislator who had lost the 1972 gubernatorial general election to the Democrat Dolph Briscoe, Jr.  On Paul's departure from the House, his seat was assumed by former state representative Tom DeLay, who would later become House Majority Leader.Answer this question using a quote from the following article:
