Projection to use for analysis of all US congressional districts?

I'm doing a project for my intro class where I am analyzing each US congressional district by compactness using area and perimeter (in order to quantify gerrymandering).

My question is which projection to use for this analysis. Presumably, each state draws their congressional districts using their own state projection, so would this mean that a reliable analysis could only be performed if I perform 50 different analyses, one for each state?

Would using a country-wide analysis not provide effective analysis?
