Just think about it. Who is George Herbert Walker? He brought Bush I's father into the business and let him marry his daughter. Bush I's father was so grateful that he named his first born son: George Herbert Walker Bush.
How would feel if you were given the name of, not your father's side but your mother's? In fact, your first 3 names (two middle names) was the exact name of your mother's father?
Then, you, yourself, named one of your sons: George Walker Bush. Pretty fukked up if you ask this anon.
