States' rights in U.S. politics refers to political powers reserved for the U.S. state governments rather than the federal government. Since the 1940s, it has often been considered a loaded term because of its use in opposition to federally mandated racial desegregation. In law, states' prerogatives are protected by the Tenth Amendment.

The balance of federal powers and those powers held by the states as defined in the Supremacy Clause of the U.S. Constitution was first addressed in the case of McCulloch v. Maryland (1819). The Court's decision by Chief Justice John Marshall asserted that the laws adopted by the federal government, when exercising its constitutional powers, are generally paramount over any conflicting laws adopted by state governments. After McCulloch, the primary legal issues in this area concerned the scope of Congress' constitutional powers, and whether the states possess certain powers to the exclusion of the federal government, even if the Constitution does not explicitly limit them to the states.

Ronald Wilson Reagan ( /ˈrɒnəld ˈwɪlsən ˈreɪɡən/; February 6, 1911 – June 5, 2004) was the 40th President of the United States, serving from 1981 to 1989. Prior to that, he was the 33rd Governor of California from 1967 to 1975 and a radio, film and television actor.

Born in Tampico, Illinois and raised in Dixon, Reagan was educated at Eureka College, earning a Bachelor of Arts degree in economics and sociology. After his graduation, Reagan moved first to Iowa to work as a radio broadcaster and then in to Los Angeles in 1937 where he began a career as an actor, first in films and later television. Some of his most notable films include Knute Rockne, All American, Kings Row, and Bedtime for Bonzo. Reagan served as president of the Screen Actors Guild, and later as a spokesman for General Electric (GE); his start in politics occurred during his work for GE. Originally a member of the Democratic Party, his positions began shifting rightward in the late 1950s, and he switched to the Republican Party in 1962. After delivering a rousing speech in support of Barry Goldwater's presidential candidacy in 1964, he was persuaded to seek the California governorship, winning two years later and again in 1970. He was defeated in his run for the Republican presidential nomination in 1968 as well as 1976, but won both the nomination and general election in 1980, defeating incumbent Jimmy Carter.

George Corley Wallace (August 25, 1919 – September 13, 1998) was an American politician and the 45th governor of Alabama, having served four nonconsecutive terms: 1963–1967, 1971–1979 and 1983–1987. After four runs for U.S. president (three as a Democrat and one on the American Independent Party ticket), he earned the title, "the most influential loser" in 20th-century U.S. politics, according to biographers Dan T. Carter and Stephan Lesher.

A 1972 assassination attempt left Wallace paralyzed, and he used a wheelchair for the remainder of his life. He is remembered for his Southern populist andsegregationist attitudes during the desegregation period, convictions that he renounced later in life. Wallace said that he did not wish to meet his Maker with unforgiven sin.

The first of four children, Wallace was born in Clio in Barbour County in southeastern Alabama, to George Corley Wallace, Sr., and the former Mozell Smith. He was the third of four generations to bear the name "George Wallace," but as neither parent liked the designation "Junior", he was called "George C." to distinguish him from his father, George, and his grandfather, a physician. Wallace's father had left college to pursue a life of farming when prices were high during World War I; Mozell had to sell their farmland to pay existing mortgages when George, Sr., died in 1937. Like his parents, Wallace was a Methodist.

Ronald Ernest "Ron" Paul (born August 20, 1935) is an American politician who has been the U.S. Representative for Texas's 14th congressional district, which includes Galveston, since 1997, and a three-time candidate for President of the United States, as a Libertarian in 1988 and as a Republican in 2008 and currently 2012. He is an outspoken critic of American foreign and monetary policies, including the Military–industrial complex and the Federal Reserve, and is known for his libertarian-leaning views, often differing from his own party on certain issues.

A native of Pittsburgh, Pennsylvania, Paul is a graduate of Gettysburg College and Duke University School of Medicine, where he earned his medical degree. He served as a medical officer in the United States Air Force from 1963 until 1968. He worked as an obstetrician-gynecologist from the 1960s to the 1980s, delivering more than 4,000 babies. He became the first Representative in history to serve concurrently with a child in the Senate when his son Rand Paul was elected to the United States Senate for Kentucky in 2010.

Thomas E. "Tom" Woods, Jr. (born August 1, 1972) is an American historian, economist, political analyst, and New York Times-bestselling author. He has written extensively on the subjects of American history, contemporary politics, and economic theory. Woods is considered a libertarian, anarcho-capitalist, and a proponent of the Austrian school of economics.

Woods graduated high school in 1990 and intended to major in math entering Harvard University. However, in a desire to strengthen his ability to argue against students supporting communism switched to majoring in history. A key turning point for the development of Woods' views was his attendance of the 1992 Mises University conference, held by the Ludwig von Mises Institute, and meeting Austro-libertarian economist Murray Rothbard while there. He then headed to Columbia University in 1994 to obtain a Ph.D. in history. He served as a history department faculty member at Suffolk County Community College in New York until 2006, and is now a scholar and senior faculty member of the Ludwig von Mises Institute (LvMI) in Auburn, Alabama, as well as a member of the editorial board for the institute's Journal of Libertarian Studies and Libertarian Papers. He is also an associate scholar of the Abbeville Institute.
