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.

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.

Non-rigid designator: 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.
