A People's History of the United States

Howard Zinn seems to cover all sides of history, and I appreciate his thoughts and commentary on how he determined what to put in his books. But I have to say, the 20th century got much more political and he continually pointed out who was president at the time events happened in the world. He seemed to blame the president (at the time) for many of the events.
Overall thought it is good to read/hear a different perspective on US History.
