The United States president preserves, protects, and defends the U.S. Constitution. Each president's term influences events in America and around the world for years to come. This biography introduces young readers to Barack Obama, the forty-forth and first African-American president of the United States. This book explores Obama's childhood, education, and early career. Readers learn how he overcame challenges and what inspired him to public service. The president's first term accomplishments are reviewed, from the American Recovery and Reinvestment Act and Patient Protection and Affordable Care Act to the elimination of Osama bin Laden and the end of the war in Iraq. Final chapters look forward to second-term goals including addressing climate change, equal rights, tax reform, and gun control. A timeline highlights President Obama's personal and professional journey, while hard-to-find photos and engaging text complete this up-close examination of this historic individual. A special section includes qualifications for the office of the presidency, the address to write President Obama, quick-reference table of all presidents and their terms, an explanation of the Electoral College process, the term of office, the job's benefits and perks, a diagram of the branches of government, and the line of presidential succession. A list of cabinet members and a list of Supreme Court appointments are also included. Glossary words in bold, an index, and phonetic spellings for those hard-to-pronounce terms, full-color and historic photographs, and primary source documents enhance and supplement the text.
