Rhetorical Case Study- Troops in Iraq

My rhetorical case study of different views on the war in Iraq couldn't have been more clearly linked to the election since it is a subject that has been brought up in debates, interviews, and published on the candidate's websites. Obama wants to bring the troops home immediately, and McCain wants to keep them in combat for as long as it is necessary to secure peace. Both couldn't disagree more, and although I would love to be bias in my paper and exert and opinion based on the research, it will also be challenging to remain unbiased and just write on the primary sources, not the subjects they are arguing.
