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.

A vice president (British English - government: vice-president; business: director) is an officer in government or business who is below a president (managing director) in rank. The name comes from the Latin vice meaning 'in place of'. In some countries, the vice president is called the deputy president. A common colloquial term for the office is vee-pee, deriving from a phonetic interpretation of the abbreviation VP.

In government, a vice president is a person whose primary responsibility is to replace the president on the event of his or her death, resignation or incapacity. Vice presidents are either elected jointly with the president as his or her running mate, elected separately, or appointed independently after the president's election.

Most, but not all, governments with vice presidents have only one person in this role at any time. If the president is not present, dies, resigns, or is otherwise unable to fulfill his or her duties, the vice president will generally serve as president. In many presidential systems, the vice president does not wield much day-to-day political power, but is still considered an important member of the cabinet. Several vice presidents in the Americas held the position of President of the Senate; this is the case, for example, in Argentina, the United States, and Uruguay. The vice president sometimes assumes some of the ceremonial duties of the president, such as attending functions and events that the actual president may be too busy to attend; the Vice President of the United States, for example, often attends funerals of world leaders on behalf of the President. In this capacity, the vice president may thus assume the role of a de facto symbolic head of state, a position which is lacking in a system of government where the powers of head of state and government are fused.

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.

Ariel Sharon (Hebrew:  אריאל שרון‎, also known by his diminutive Arik, אַריק, born Ariel Scheinermann, אריאל שיינרמן on 26 February 1928) is an Israeli statesman and retired general, who served as Israel’s 11th Prime Minister. He has been in a permanent vegetative state since suffering a stroke on 4 January 2006.

Sharon was a commander in the Israeli Army since its inception in 1948. As a paratrooper and then officer he participated prominently in the 1948 War of Independence, becoming platoon commander of the Alexandroni Brigade and taking part in many battles, including Operation Ben Nun Alef. He was an instrumental figure in the creation of Unit 101, the Retribution operations, the 1956 Suez War, the Six-Day War of 1967, the War of Attrition and the Yom-Kippur War of 1973. As Minister of Defense, he directed the 1982 Lebanon War. During his military career, he was considered the greatest Field Commander in Israel's history, and one of the country's greatest ever military strategists. After his assault of the Sinai in the Six-Day War and his encirclement of the Egyptian Third Army in the Yom Kippur War, the Israeli public nicknamed him "The King of Israel" and "The Lion of God".

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 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.
