20th-century American legislators

Daniel David Rostenkowski (January 2, 1928 – August 11, 2010) was a United States Representative from Chicago, serving for 36 years, from 1959 to 1995. He became one of the most powerful legislators in Congress, especially in matters of taxation. He was imprisoned in 1996. A Democrat and son of a Chicago alderman, Rostenkowski was for many years Democratic Committeeman of Chicago's 32nd Ward, retaining this position while also serving in Congress.In national politics, he rose by virtue of seniority to the rank of Chairman of the House Ways and Means Committee in 1981. As Chairman of the Ways and Means Committee, he played a critical role in formulating tax policy during the Republican administration of Ronald Reagan, including the Economic Recovery Tax Act of 1981, which cut the top federal bracket to 50%, and the Tax Reform Act of 1986, which further lowered it to 28% and reduced the number of brackets to only two. He was also involved in trade policy, as well as reforms of the welfare system, health care, and Social Security programs.Rostenkowski closed legislative deals between the toughest power brokers in the U.S., from union chiefs to corporate titans to president Reagan and to everyone in between. The book Chicago and the American Century credits Rostenkowski with securing billions of dollars in federal money for projects in Chicago and Illinois. The book named him the sixth most significant politician to come from Chicago in the entire twentieth century.Rostenkowski's political career, however, ended abruptly in 1994 when he was indicted on corruption charges relating to his role in the Congressional Post Office Scandal, and then narrowly defeated for reelection by Republican Michael Patrick Flanagan. He subsequently pleaded guilty to charges of mail fraud in 1996 and was fined and sentenced to 17 months in prison. In December 2000, President Bill Clinton pardoned Rostenkowski.

Donald Edgar "Buz" Lukens (February 11, 1931 – May 22, 2010) was a Republican member of the United States House of Representatives from Ohio. His political career ended in 1990 when he was charged with contributing to the delinquency of a minor. Six years later, he was convicted for accepting a bribe during his time in Congress.

Morris King Udall (June 15, 1922 – December 12, 1998) was an American attorney and Democratic politician who served as a U.S. representative from Arizona from May 2, 1961, to May 4, 1991. He was a leading contender for the 1976 Democratic presidential nomination. He was noted by many for his independent and liberal views.In 1961, Udall won a special election to succeed his brother, Stewart Udall, as the congressman for Arizona's 2nd congressional district. In Congress, the younger Udall became a prominent and popular figure for his independent ways, his leading role in the conservation and environmental protection movements, his key role in reforming Congress and political campaigns, and his pioneering role in opposing the Vietnam War.Udall sought the Democratic Party nomination in the 1976 presidential election, but was defeated by Jimmy Carter. He supported Ted Kennedy's strong challenge to Carter in the 1980 Democratic primary, and delivered the keynote address at the 1980 Democratic National Convention.He served as Chairman of the House Interior Committee from 1977 to 1991. Diagnosed with Parkinson's disease in 1980, Udall resigned from Congress in 1991 as the effects of the disease worsened. He died in 1998. His son, Mark Udall, represented Colorado in the United States Senate from 2009 to 2015, and his nephew Tom Udall served as a United States Senator from New Mexico from 2009 to 2021. Both also served multiple terms in the U.S. House of Representatives.

He was a Democrat from Kentucky who represented the state in the United States Senate from 1973 until 1985. He was defeated for re-election in 1984 by Mitch McConnell by 5,269 votes.

David Ernest Duke (born July 1, 1950) is an American politician, white supremacist, antisemitic conspiracy theorist, and former grand wizard of the Knights of the Ku Klux Klan. From 1989 to 1992, he was a member of the Louisiana House of Representatives for the Republican Party. His politics and writings are largely devoted to promoting conspiracy theories about Jews, such as Holocaust denial and Jewish control of academia, the press, and the financial system. In 2013, the Anti-Defamation League called Duke "perhaps America's most well-known racist and anti-Semite".Duke unsuccessfully ran as a Democratic candidate for state legislature during the 1970s and 1980s, culminating in his campaign for the 1988 Democratic presidential nomination. After failing to gain any traction within the Democratic Party, he gained the presidential nomination of the minor Populist Party. In December 1988, he became a Republican and claimed to have become a born-again Christian, nominally renouncing antisemitism and racism. He soon won his only elected office, a seat in the Louisiana House of Representatives. He then ran unsuccessful but competitive campaigns for several more offices, including United States Senate in 1990 and governor of Louisiana in 1991. His campaigns were denounced by national and state Republican leaders, including President George H. W. Bush. He mounted a minor challenge to President Bush in 1992.
By the late 1990s, Duke had abandoned his pretense of rejecting racism and antisemitism, and began to openly promote racist and neo-Nazi viewpoints. He then began to devote himself to writing about his political views, both in newsletters and later on the Internet. In his writings, he denigrates African Americans and other ethnic minorities, and promotes conspiracy theories about a Jewish plot to control America and the world. He continued to run for public office through 2016, but after his reversion to open neo-Nazism, his candidacies were not competitive.
During the 1990s, Duke defrauded his political supporters by pretending to be in dire financial straits and soliciting money for basic necessities. At the time, he was in fact financially secure and used the money for recreational gambling. In December 2002, Duke pleaded guilty to felony fraud and subsequently served a 15-month sentence at Federal Correctional Institution, Big Spring in Texas.

Robert Bruce Mathias (November 17, 1930 – September 2, 2006) was an American decathlete, politician, and actor. Representing the United States, he won two Olympic gold medals in the Decathlon, at the 1948 and the 1952 Summer Games. As a Republican, he served in the US House of Representatives for California's 18th congressional district, for four terms from 1967 to 1975.

Henry Martin Jackson (May 31, 1912 – September 1, 1983), also known as Scoop Jackson, was an American lawyer and politician who served as a U.S. representative (1941–1953) and U.S. senator (1953–1983) from the state of Washington. A Cold War liberal and anti-Communist member of the Democratic Party, Jackson supported higher military spending and a hard line against the Soviet Union, while also supporting social welfare programs, civil rights, and labor unions.Born in Everett, Washington, to Norwegian immigrants, Jackson practiced law in Everett, after graduating from the University of Washington School of Law. He won election to Congress in 1940, and joined the Senate in 1953 after defeating incumbent Republican Party senator Harry P. Cain. Jackson supported the civil rights movement of the 1960s, and authored the National Environmental Policy Act, which helped establish the principle of publicly analyzing environmental impacts. He co-sponsored the Jackson–Vanik amendment, which denied normal trade relations to countries with restrictive emigration policies. Jackson served as chairman of the United States Senate Committee on Energy and Natural Resources from 1963 to 1981. He was twice an unsuccessful candidate for the Democratic Party nomination in the 1972 and 1976 presidential elections. While still serving in the Senate, Jackson died in 1983.
His political beliefs were characterized by support of civil rights, human rights, and safeguarding the environment but with an equally strong commitment to oppose totalitarianism in general and — with the start of the Cold War — Communist rule in particular. Jackson's political philosophies and positions have been cited as an influence on a number of key figures associated with neoconservatism, including Paul Wolfowitz and Richard Perle, both of whom previously served as aides to Jackson. The Seattle-based Henry M. Jackson Foundation was created in 1983 by his former colleagues and staff, as well as his widow and other family members, to further his work. In 1987, the Department of Defense gave to the Jackson Foundation a one-time, $10 million appropriation for its endowment, in honor of the Senator. To date, the Foundation has awarded over $26 million in grants to educational and non-profit institutions. Jackson also sponsored legislation to form the Foundation to Advance Military Medicine, which was later renamed in his honor at the time of his death, to the Henry M. Jackson Foundation for the Advancement of Military Medicine.
