2. According to Don Kettl: "The conflicts inherent in the role that boundaries play have long made stable boundaries impossible to draw. As a result, both politics and administration have struggled over time as to just where key boundaries ought to be, and the system has accommodated itself to the inevitable uncertainties that surround these cross-pressures. However, new problems are emerging that make even short-term accommodations hard to find.
