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.

Paul Davis Ryan (born January 29, 1970) is the U.S. Representative for Wisconsin's 1st congressional district, serving since 1999. He is a member of the Republican Party, and has been ranked among the party's most influential voices on economic policy.

Born and raised in Janesville, Wisconsin, Ryan graduated from Miami University in Ohio and later worked as a marketing consultant for Ryan Incorporated Central, run by a branch of his family. In the mid to late 1990s, he worked as an aide to United States Senator Bob Kasten, as legislative director for Senator Sam Brownback of Kansas, and as a speechwriter for former U.S. Representative and 1996 Republican vice presidential nominee Jack Kemp of New York. In 1998, Ryan won election to the United States House of Representatives, succeeding the two-term incumbent, fellow Republican Mark Neumann.

Ryan currently chairs the House Budget Committee, where he has played a prominent public role in drafting and promoting the Republican Party's long-term budget proposal. He introduced a plan, The Path to Prosperity, in April 2011 as an alternative to the budget proposal of President Barack Obama, and helped introduce The Path to Prosperity: A Blueprint for American Renewal in March 2012, in response to Obama's 2013 budget. Ryan is one of the three co-founders of the Young Guns Program, an electoral recruitment and campaign effort by House Republicans. He endorsed Republican presidential candidate and former Governor of Massachusetts Mitt Romney for the 2012 United States presidential election. Ryan has been considered as a possible running mate for Romney.

John Forbes Kerry (born December 11, 1943) is the senior United States Senator from Massachusetts, the 10th most senior United States Senator and chairman of the Senate Foreign Relations Committee. He was the presidential nominee of the Democratic Party in the 2004 presidential election, but lost to then President George W. Bush.

The son of an Army Air Corps serviceman, Kerry was born in Aurora, Colorado. He attended boarding school in Massachusetts and New Hampshire and went on to graduate from Yale University class of 1966, where he majored in political science. He enlisted in the Naval Reserve in 1966 and, during 1968-1969, served a four-month tour of duty in South Vietnam as officer-in-charge (OIC) of a Swift Boat. For that service he was awarded several combat medals that include the Silver Star, Bronze Star, and three Purple Hearts. After returning to the United States, Kerry joined the Vietnam Veterans Against the War in which he served as a nationally recognized spokesperson and as an outspoken opponent of the Vietnam war. During that period, he appeared before the Senate Committee on Foreign Affairs where he deemed United States war policy in Vietnam to be the cause of "war crimes".
