Who wants to help me with my history essays?

There are the two possible essays. I’m trying to make outlines for both so I can have something prepared when my professor gives us the final. I feel like there’s a lot to write though just because each question spans a long time in history.

1. Trace American foreign affairs from the end of the Civil War to the Obama Administration. What key principles guided American foreign policy? What were the important turning points that affected the U.S. role in the world?

2. Discuss the presidential elections from 1900 to 2008. What were the major policy issues? What patterns have remained constant in American presidential politics?
