While I can appreciate the outpouring of joy in the wake of President-elect Barack Obama’s historic win, I was struck by how many people were talking as if they were now living in the land of milk and honey, where dogs and cats and Keith Olbermann and Bill O’Reilly all get along. Change is certainly coming, but it’s not all going to be inevitable and unstoppable. At some point the courts are going to stop some initiative — or at least slow it down.

That should be a sobering thought for Obama’s supporters — and one piece of encouragement for Republicans.
