I just need some ideas please. I have to trace a policy example through the 3 models of federalism, dual, cooperative and creative. I have done quite bit of research and am having trouble finding a policy that I will be able to trace through the 3 models and actually understand what Im reading and writing about. Please give me some ideas. Thanks!

Congradulatiolns. Few models of government lend themselves to rational understanding, in my experience.

Policies you might consider: Property taxes, sales taxes, tariffs, free public education (accessible to all regardless of race, ethnicity, or handicaps).
