Presidential Cabinets

The introduction could include the positions in the presidential cabinet. The paper should represent the relationships between presidents and their cabinets. The focus of the relationships will only need to be examined from Jimmy Carter through Obama. The purpose is to view the efficiencies of these relationships or lack thereof, and denote if these relationships were effective in initiating policy or interacting with Congress. For example, Jimmy Carter was extremely self reliant taking most matters into his own hands as George W. was very much of a minimalist, sometimes not even knowing of certain implementations within his cabinet. These are really the only guidelines. Please, let me know if anything else should be needed.Thank you!
