Dorothy Walker Bush Koch, often called "Doro", (born August 18, 1959) is an American author and philanthropist.

George Walker Bush (born July 6, 1946) is an American politician who served as the 43rd President of the United States from 2001 to 2009.
 He was also the 46th Governor of Texas from 1995 to 2000.
 After graduating from Yale University in 1968 and Harvard Business School in 1975, he worked in the oil industry.
 Bush married Laura Welch in 1977 and ran unsuccessfully for the House of Representatives shortly thereafter.
 He later co-owned the Texas Rangers baseball team before defeating Ann Richards in the 1994 Texas gubernatorial election.
 Bush was elected president in 2000 after a close and controversial win over Democratic rival Al Gore, becoming the fourth president to be elected while receiving fewer popular votes than his opponent.
The presidency of George W. Bush began at noon EST on January 20, 2001, when George W. Bush was inaugurated as 43rd President of the United States, and ended on January 20, 2009.
 Bush, a Republican, took office following a very close win over Democratic nominee Al Gore in the 2000 presidential election.
 Bush, the 43rd president, is the eldest son of the 41st president, George H. W. Bush.
 Bush was re-elected in 2004, defeating his Democratic opponent John Kerry.

George Herbert Walker Bush (born June 12, 1924) is an American politician who was the 41st President of the United States from 1989 to 1993 and the 43rd Vice President of the United States from 1981 to 1989.
 A member of the Republican Party, he was previously a congressman, ambassador, and Director of Central Intelligence.
 He is the oldest living former President and Vice President.
 Previously known as simply "George Bush", since 2001, Bush has often been referred to as "George H. W. Bush", "Bush 41", "Bush the Elder", or "George Bush Senior" to distinguish him from his eldest son, George W. Bush, the 43rd President of the United States.
For example, consider the phrase "The 43rd President of the United States of America": while the 43rd President of the United States is "actually" George W. Bush, things might have been different.
 Bush might have lost the election, meaning that the 43rd President might have been Al Gore or Ralph Nader instead.
 ("How remote" these possible worlds are from the actual world is a discussion for physics and counterfactualism.)
 "The 43rd President of the United States of America" is thus a non-rigid designator, picking out George W. Bush in some possible worlds, Al Gore in others, and yet other people in other worlds.
