Your paper proposal should follow this format:
1) Your name
2) Your main thesis or what you want to write about
3) The main relationship that you want to examine
Here is an example:
I am interested in whether poor people turned out during the Depression.
My main relationship I want to examine is whether poverty is positively related to turnout in a Depression year. I will compare this to poverty and turnout in a non-Depression year. I will also control for how much a respondent liked FDR.
