Your goal is to show that Obama's plans are a burden on college students?
It's really hard to answer this question, without knowing what data is available in the first place. Yes, it would be good to look at Obama's plans related to college students, and possibly planned tax cuts for people in certain income brackets, and also maybe at some of the bailout package, and healthcare policies, etc. It would also be worth looking at the respective policies of the previous administration, for comparison.
First though, I would re-define what you are looking for. If you are trying to prove that Obama is doing college students a disservice, you will likely bias your investigation, and your results will be unreliable.
It would be more useful to instead research "what effect" Obama's plans have on college students.
