The Essence of Bush

President Bush and his wife graced Europe this week. London had the privilege of their company over the weekend. I just saw the first couple's first ever television interview together for a British television channel. Mr. President quite categorically stated that he would like to be remembered as "a principled man who did not compromise on his core values".

Can someone please elucidate on these "core values". I am just finding it a little difficult to drill the sea of principles and zero in on the oil of essence that the President is referring to.

Have a great week ahead!
