The Republican Party is one of the two major contemporary political parties in the United States, along with the Democratic Party. Founded by anti-slavery expansion activists in 1854, it is often called the GOP (Grand Old Party), although the rival Democratic Party is older. Eighteen US presidents have been Republicans. The party's platform generally reflects American conservatism in the U.S. political spectrum. American conservatism of the Republican Party is not wholly based upon rejection of the political ideology of liberalism, as many principles of American conservatism are based upon classical liberalism. Rather the Republican Party's conservatism is largely based upon its support of classical liberal principles against the modern liberalism of the Democratic Party that is considered American liberalism in contemporary American political discourse.

In the 112th Congress, elected in 2010, the Republican Party holds a majority of seats in the House of Representatives and a minority of seats in the Senate. The party holds the majority of governorships as well as the majority of state legislatures.

Stephen Tyrone Colbert ( /koʊlˈbɛər/ or /ˈkoʊlbərt/; born May 13, 1964) is an American political satirist, writer, comedian, television host, and actor. He is the host of Comedy Central's The Colbert Report, a satirical news show in which Colbert portrays a caricatured version of conservative political pundits.

Colbert originally studied to be an actor, but became interested in improvisational theatre when he met famed Second City director Del Close while attending Northwestern University. He first performed professionally as an understudy for Steve Carell at Second City Chicago; among his troupe mates were comedians Paul Dinello and Amy Sedaris, with whom he developed the critically acclaimed sketch comedy series Exit 57.

Colbert also wrote and performed on the short-lived Dana Carvey Show before collaborating with Sedaris and Dinello again on the cult television series Strangers with Candy. He gained considerable attention for his role on the latter as closeted gay history teacher Chuck Noblet. It was his work as a correspondent on Comedy Central's news-parody series The Daily Show, however, that first introduced him to a wide audience.

Newton Leroy "Newt" Gingrich ( /ˈnjuːt ˈɡɪŋɡrɪtʃ/; born Newton Leroy McPherson; June 17, 1943) is an American politician, author, and political consultant. He represented Georgia's 6th congressional district as a Republican from 1979 until his resignation in 1999, and served as the 58th Speaker of the U.S. House of Representatives from 1995 to 1999. Gingrich was a candidate for the 2012 Republican Party presidential nomination.

In the 1970s, Gingrich taught history and geography at the University of West Georgia. During this period he ran twice (1974 and 1976) for the United States House of Representatives before winning in November 1978. He served as House Minority Whip from 1989 to 1995.

A co-author and architect of the "Contract with America", Gingrich was a major leader in the Republican victory in the 1994 congressional election. In 1995, Time named him "Man of the Year" for "his role in ending the four-decades-long Democratic majority in the House". While he was House speaker, the House enacted welfare reform, passed a capital gains tax cut in 1997, and in 1998 passed the first balanced budget since 1969. The poor showing by Republicans in the 1998 Congressional election and pressure from Republican colleagues caused Gingrich's resignation from the speakership on November 5, 1998, and then the House on January 3, 1999.

Benjamin Solomon "Ben" Carson, Sr., (born September 18, 1951) is an American neurosurgeon and the Director of Pediatric Neurosurgery at Johns Hopkins Hospital. He was awarded the Presidential Medal of Freedom, the highest civilian award in the United States, by President George W. Bush in 2008.

Carson was born in Detroit, Michigan and was raised by his single mother, Sonya Carson. He struggled academically throughout elementary school, but started to excel in middle school and throughout high school. After graduating with honors from his high school, he attended Yale University, where he earned a degree in Psychology. He chose to go to Yale because in College Bowl, an old TV program, he saw Yale compete against and defeat many other colleges in knowledge, including Harvard. Carson wanted to participate in College Bowl, but the program was discontinued. From Yale, he attended University of Michigan Medical School.

Carson's eye-hand coordination and three-dimensional reasoning skills made him a gifted surgeon. After medical school he became a neurosurgery resident at Johns Hopkins Hospital in Baltimore. Starting off as an adult neurosurgeon Carson became more interested in pediatrics. With children he believed that "what you see is what you get, ... when they’re in pain they clearly show it with a frown on their face or when they are happy they show it by smiling brightly." Since then he has been the head of the pediatric neurosurgeon department.
