Working in state legal counsel throughout the 1970s, he made an unsuccessful run for Lieutenant Governor of Illinois in 1978. He was elected to the U.S. House of Representatives in 1982, representing the Springfield-based 20th congressional district. In 1996, he won election to the U.S. Senate by an unexpected 15-point margin. He has served as Senate Democratic Whip since 2005, and for a period of eight years (2007–2015) served as the Senate Majority Whip.

Ted Cruz

Rafael Edward "Ted" Cruz (born December 22, 1970) is an American politician and the junior United States Senator from Texas. He is a candidate for the Republican nomination for President of the United States, in the 2016 presidential election.

Cruz graduated from Princeton University in 1992, and from Harvard Law School in 1995. Between 1999 and 2003, Cruz was the director of the Office of Policy Planning at the Federal Trade Commission, an associate deputy attorney general at the United States Department of Justice, and domestic policy advisor to President George W. Bush on the 2000 George W. Bush presidential campaign. He served as Solicitor General of Texas from 2003 to 2008, appointed by Texas Attorney General Greg Abbott. He was the first Hispanic, and the longest-serving solicitor general, in Texas history. From 2004 to 2009, Cruz was also an adjunct professor of law at the University of Texas School of Law in Austin, where he taught U.S. Supreme Court litigation.

Cruz ran for the Senate seat vacated by fellow Republican Kay Bailey Hutchison, and in July 2012 defeated Lieutenant Governor David Dewhurst during the Republican primary runoff, 57%–43%. Cruz then defeated former state Representative Paul Sadler in the November 2012 general election, winning 56%–41%. He is the first Hispanic American to serve as a U.S. senator representing Texas, and is one of three Senators of Cuban descent. Cruz chairs the United States Senate Judiciary Subcommittee on Oversight, Federal Rights and Agency Activities, and is also the chairman of the United States Senate Commerce Subcommittee on Space, Science and Competitiveness. In November 2012, he was appointed vice-chairman of the National Republican Senatorial Committee.

Bernie Sanders

Bernard "Bernie" Sanders (born September 8, 1941) is an American politician and the junior United States Senator from Vermont. He is a candidate for the Democratic nomination for President of the United States in the 2016 U.S. presidential election. A Democrat as of 2015, Sanders had been the longest-serving independent in U.S. congressional history, though his caucusing with the Democrats entitled him to committee assignments and at times gave Democrats a majority. Sanders has been the ranking minority member on the Senate Budget Committee since January 2015, and previously served for two years as chair of the Senate Veterans' Affairs Committee.

Sanders was born and raised in the New York City borough of Brooklyn and graduated from the University of Chicago in 1964. While a student, he was an active civil rights protest organizer for the Congress of Racial Equality and the Student Nonviolent Coordinating Committee. After settling in Vermont in 1968, Sanders ran unsuccessful third-party campaigns for governor and U.S. senator in the early to mid-1970s. As an independent, he was elected mayor of Burlington, Vermont's most populous city, in 1981, and was reelected three times. In 1990, he was elected to represent Vermont's at-large congressional district in the U.S. House of Representatives. In 1991, Sanders co-founded the Congressional Progressive Caucus. He served as a congressman for 16 years before being elected to the U.S. Senate in 2006. In 2012, he was reelected with 71% of the popular vote. During the 2016 presidential primaries, Sanders became the first self-described democratic socialist and first Jewish American to win a presidential primary of a major party, namely the New Hampshire primary.

John McCain

John Sidney McCain III (born August 29, 1936) is the senior United States Senator from Arizona. He was the Republican presidential nominee in the 2008 United States presidential election.

McCain followed his father and grandfather, both four-star admirals, into the United States Navy, graduating from the U.S. Naval Academy in 1958. He became a naval aviator, flying ground-attack aircraft from aircraft carriers. During the Vietnam War, he was almost killed in the 1967 USS Forrestal fire. In October 1967, while on a bombing mission over Hanoi, he was shot down, seriously injured, and captured by the North Vietnamese. He was a prisoner of war until 1973. McCain experienced episodes of torture, and refused an out-of-sequence early repatriation offer. His war wounds left him with lifelong physical limitations.

He retired from the Navy as a captain in 1981 and moved to Arizona, where he entered politics. Elected to the U.S. House of Representatives in 1982, he served two terms, and was then elected to the U.S. Senate in 1986, winning re-election easily four times, most recently in 2010. While generally adhering to conservative principles, McCain at times has had a media reputation as a "maverick" for his willingness to disagree with his party on certain issues. After being investigated and largely exonerated in a political influence scandal of the 1980s as a member of the Keating Five, he made campaign finance reform one of his signature concerns, which eventually led to the passage of the McCain-Feingold Act in 2002. He is also known for his work towards restoring diplomatic relations with Vietnam in the 1990s, and for his belief that the war in Iraq should be fought to a successful conclusion. McCain has chaired the Senate Commerce Committee, opposed spending that he considered to be pork barrel, and played a key role in alleviating a crisis over judicial nominations.

Barack Obama

Barack Hussein Obama II (US ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is an American politician serving as the 44th President of the United States, the first African American to hold the office. Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he served as president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney and taught constitutional law at University of Chicago Law School between 1992 and 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004, and ran unsuccessfully in the Democratic primary for the United States House of Representatives in 2000 against incumbent Bobby Rush.

In 2004, Obama received national attention during his campaign to represent Illinois in the United States Senate with his victory in the March Democratic Party primary, his keynote address at the Democratic National Convention in July, and his election to the Senate in November. He began his presidential campaign in 2007 and, after a close primary campaign against Hillary Rodham Clinton in 2008, he won sufficient delegates in the Democratic Party primaries to receive the presidential nomination. He then defeated Republican nominee John McCain in the general election, and was inaugurated as president on January 20, 2009. Nine months after his inauguration, Obama was named the 2009 Nobel Peace Prize laureate.
