Definition of BLUE BLOOD
1 : membership in a noble or socially prominent family
*****************************************************
George H. W. Bush’s father was Prescott Bush, a US Senator and banker, and served on the board of CBS and as a member of the Yard Corporation, the body that runs Yale.
His father, Samuel Bush was a railroad executive, then a steel company president, and, during World War I, also a federal government official in charge of coordination and assistance to major weapons contractors.
Can anyone seriously say the the above definition does not apply to the Bush family? Stating someone is a “blueblood” is does not mean someone is a bad person, or lacking in character. It simply indicates a person’s background that likely gives someone an elitist worldview.
I have always thought that GHWB is more of a gentleman than Bar is a lady.
On wiki you can take it back to G W Bush’s Great, Great, Great, Great Grandfather who was a young man during the Revolution. His Great, Great, Great Grandfather was an abolitionist who tried to get NY to secede over slavery, then went to California as a 49’er. His Great, Great Grandfather was an Episcopal priest, which in New Jersey, where he lived, made him definitely in the upper crust.
