Who is Prepared to be President? Nobody!

The toughest job in the world is essentially reactive. The president does not run the country and is not paid by the hour. He is there to respond to events unanticipated: bizarre attacks on New York City, the blockade of a European city occupied by American troops, the rising of young black men and women against legal segregation, civil wars and genocides in places we never knew existed, the shelling of an American fort off South Carolina by other Americans.Presidents are alone, facing the unknown. The job is not about running the country; it is about leading the nation in unexpected crisis or danger. No one remembers whether Lincoln balanced the budget."
