Brian Murphy: Hand on heart, Obama knows this speech must really count
Richard Nixon's advice to Barack Obama today would be keep it short.
In preparing for his swearing-in ceremony in 1969, Nixon read the inaugural speeches of each of his predecessors. His assessment was that "only the short ones are remembered".
Today, Barack Obama will make his second inaugural address as President of the United States of America. If Mr Obama has followed Mr Nixon's meticulous preparations, he will have had plenty of material to ponder.
