2. Franklin Delano Roosevelt
SRI Ranking: 3
Brookings Institution Ranking: 1
FDR spent 12 years in the White House, a record that will never be broken, barring the abolition of the Twenty-second Amendment. His four terms very among the most turbulent in nation’s history, but he managed to leave to his successor the strongest country, both militarily and economically, in the world. If an expansion of the Mount Rushmore is to be made, it would be almost certain that FDR’s face join the previous four presidents carved in granite.
