Abraham Lincoln. Theodore Roosevelt. Franklin Delano Roosevelt. Lyndon B. Johnson. They grew up and lived in very different worlds - Lincoln was poor and uneducated, his frontier cabin home deep in the harsh wilderness; Theodore Roosevelt hailed from an elegant home in the heart of New York City and travelled the world with his family; Franklin Roosevelt loved the outdoors surrounding his family´s rural estate where he was the centre of attention; and Lyndon Johnson´s modest childhood home had no electricity or running water but provided a window into Texas politics. So how did each of them do it - rise to become President of the United States? What did these four kids have individually - and have in common - that made them the ones to lead the country through some of its most turbulent times?
