In the United States, Super Tuesday, in general, refers to the Tuesday in February or March of a presidential election year when the greatest number of states hold primary elections to select delegates to national conventions at which each party's presidential candidates are officially nominated. More delegates can be won on Super Tuesday than on any other single day of the primary calendar; accordingly, candidates seeking the presidency traditionally must do well on this day to secure their party's nomination. In 2008, Super Tuesday was February 5; 24 states held primaries or caucuses on this date, with 52% of all pledged Democratic Party delegates and 49% of the total Republican Party delegates at stake.The 2012 Super Tuesday was held on March 6, 2012.

Since Super Tuesday primaries are typically held in a large number of states from geographically and socially diverse regions of the country, Super Tuesday typically represents a presidential candidate's first test of national electability. Convincing wins in Super Tuesday primaries have usually propelled candidates to their party's nomination. The particular states holding primaries on Super Tuesday have varied from year to year.

Larry King (born November 19, 1933) is an American television and radio host whose work has been recognized with awards including two Peabodys and ten Cable ACE Awards. He began as a local Florida journalist and radio interviewer in the 1950s and 1960s and became prominent as an all-night national radio broadcaster starting in 1978. From 1985-2010, he hosted the nightly interview TV program Larry King Live on CNN.

King was born Lawrence Harvey Zeiger in Brooklyn, New York City, to an Austrian immigrant Edward Zeiger, a restaurant owner and defense plant worker, and his wife Jennie Gitlitz, a garment worker, who emigrated from Belarus. King grew up in a religiously observant Jewish home, but in adulthood became an agnostic.

King's father died at 44 of heart disease, and his mother had to go on welfare to support her two sons. His father's death greatly affected King, and he lost interest in school. After graduating from high school, he worked to help support his mother. From an early age, however, he had wanted to go into radio. King is a fan of the Los Angeles Dodgers.
