After the Chappaquiddick incident in 1969, Ted Kennedy fell from front runner to non-candidate. Ed Muskie was the establishment favorite until he was reported to have cried emotionally during a speech defending himself against the Canuck letter. George McGovern was able to gain ground and make a strong showing in New Hampshire. George Wallace ran as an outsider and did well in the South. His campaign was ended when an assassin shot him and left him paralyzed. McGovern went on to win a majority of the delegates and the nomination at the convention. However, his prior efforts to reform the nomination process had reduced the power of Democratic Party leaders. McGovern had difficulty getting a vice presidential running mate to run with him. It then took hours to get him approved. A couple weeks later it was revealed that Thomas F. Eagleton had undergone electroshock therapy for depression. After claiming to back Eagleton "1000%", McGovern asked him to resign three days later. After a week of being publicly rebuffed by prominent Democrats, McGovern finally managed to get Sargent Shriver to be his new running mate. This trouble compounded the already weak support he had among party leaders.

Joseph Robinette "Joe" Biden, Jr. (pronunciation: /ˈdʒoʊsɨf rɒbɨˈnɛt ˈbaɪdən/; born November 20, 1942) is the 47th and current Vice President of the United States, serving under President Barack Obama. A Democrat, he was a United States Senator from Delaware from January 3, 1973 until his resignation on January 15, 2009, following his election to the Vice Presidency.

Biden was born in Scranton, Pennsylvania and lived there for ten years before moving to Delaware. He became an attorney in 1969, and was elected to a county council in 1970. Biden was first elected to the Senate in 1972 and became the sixth-youngest senator in U.S. history. He was re-elected to the Senate six times, was the fourth most senior senator at the time of his resignation, and is the 15th-longest serving Senator in history. Biden was a long-time member and former chairman of the Foreign Relations Committee. His strong advocacy helped bring about U.S. military assistance and intervention during the Bosnian War. He opposed the Gulf War in 1991. He voted in favor of the Iraq War Resolution in 2002, but later proposed resolutions to alter U.S. strategy there. He has also served as chairman of the Senate Judiciary Committee, dealing with issues related to drug policy, crime prevention, and civil liberties, and led creation of the Violent Crime Control and Law Enforcement Act and Violence Against Women Act. He chaired the Judiciary Committee during the contentious U.S. Supreme Court nominations of Robert Bork and Clarence Thomas.

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.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the 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 in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.

Upton Beall Sinclair Jr. (September 20, 1878 – November 25, 1968), was an American author and one-time candidate for governor of California who wrote close to one hundred books in many genres. He achieved popularity in the first half of the twentieth century, acquiring particular fame for his classic muckraking novel, The Jungle (1906). It exposed conditions in the U.S. meat packing industry, causing a public uproar that contributed in part to the passage a few months later of the 1906 Pure Food and Drug Act and the Meat Inspection Act.Time magazine called him "a man with every gift except humor and silence."

Sinclair was born in Baltimore, Maryland to Upton Beall Sinclair and Priscilla Harden. His father was a liquor salesman whose alcoholism shadowed his son's childhood. Priscilla Harden Sinclair was a strict Episcopalian who disliked alcohol, tea, and coffee. Her lineage was of great affluence. Her parents were very prosperous in Baltimore and her sister married a millionaire. Sinclair had wealthy grandparents with whom he often stayed. This gave him insight into how both the rich and the poor lived during the late nineteenth century. Living in two social settings affected him and greatly influenced his books. Upton Beall Sinclair Sr. was also from a highly respected family in the south, but due to the Civil War and Reconstruction, the family's wealth evaporated and the family became ruined.
