If I should add one famous president at the Mount Rushmore, after Washington, Jefferson, Roosevelt and Lincoln, it would be, without any doubt, Barack Obama.                                                                                                  If the fourth were chosen to represent the birth and growth of the nation, Obama is the symbol of the emergence of a progressive America . A new America based on the melting pot, based on the tolerance. Obviously, he is the one who marked the country especially after the famous speech of Martin Luther King "I have a Dream".  Among all presidents, among all famous american people, I guess Barack Obama deserves to have his face engraved forever in the Mountain rock. It would be a very symbolic gesture especially as the man who engraved the four presidents was a member of the ku klux klan. Obama is a strong symbol of a new America, a strong symbol of the twenthieth century. Despite all, I guess one day, we could see him engraved for ever among the four presidents. To sum up, in all sincerity it lacks only him!
