It's Always Time for a Change - Slate Video

The one thing that never changes in presidential campaigns is the promise of change. In this "Damned Spot Classic," David Schwartz of the Museum of the Moving Image shows us how campaign spots dating back 50 years have used the same theme. As has been noted by many of the green bloggers out there, the candidates better start talking about the environment soon, or there won't be any planet left to change. Why have they all been so quiet on this? Why is Al gore the only one paying attention? Unfortunately, it seems like the impact of "The Inconvenient Truth" may have faded into the background, much like the melting glaciers, only to jarr us to a new reality soon enough.
