The Audacity of Hope is memoir written by United States senator, Barack Obama of Chicago, Illinois. The story takes place in Washington D.C. The main character (the protagonist) of the book is Barack Obama. Barack Obama is a skeptical person. He is an attorney, senator, husband, Christian, and father. Barack Obama's memoir describes a time in his life when he is elected into the United States Senate on January 4th 2005. Obama reflects on what he feels are critical issues that he has faced personally in his life. They include abortion, The War On Terror, democrats, republicans etc. The important issues facing our nation, Obama talks about are: immigration, health care, abortion etc. A senator of the United States Senate, Barack Obama tells about his experiences in Washington D.C. He talks about his family. Being a son of an African father and a white American mother wasn't easy for him. It grows out of the conversations on the campaign trail. The main idea or topic of this book is how we might begin the process of changing our politics and our civic life. He explains the Constitution. This book I think can explain to people or readers about politics and his ideas.
