Kepner and Keyes Agree Once Again

The first question of the debate dealt with how each candidate differentiates between state and federal power? Molly believes states should focus on things that affect it directly, such as education, and the federal government should handle things that focus on the entire country, such as war.  Carolyn's response was pretty much the same thing, so both candidates agreed, yet again.  I agree with both of the candidates, but where will the line be drawn between what affects the states and what affects the entire nation? Pretty much anything can affect both, so who has the power?
