State/local conflicts, the new pre-emption and American federalism

The paper takes as its point of departure the 'new' doctrine of pre-emption (between states and cities) in the US to reflect upon the apparent conflict between federalism theory (which advances certain values that cities are in a better position to foster) and formal federalism (which is all about states as the main units). The paper also reflects upon the theory underlying the relationship between federalism, localism and the city more generally.
