The election of Barack Obama as the first African American president of the United States made history. He grew up in the sixties and seventies, a time of great change in the US, and saw that some things in the country were wrong and need to be addressed-- and he kept looking for platforms where he could help. Krensky provides information about his life, from his birth in 1961 to the present. Even with the presidency behind him, Obama remains a force for good. -- adapted from page 6, author's note to the reader.
