The President of the United States of America is one of the world’s most powerful and influential leaders. There is no doubt that many of the 44 Presidents in the United States’ almost 240 years of existence, have had the toughest job in the world, leading in times of great peril including a civil war, world wars and economic disaster. Success has varied from one President to the next, as each faced a host of challenges as they lead their nation and people.
