It looks like Obama's budget intends to give up on implementing the Yucca Mountain nuclear waste repository. (Congratulations, Senate Majority Leader Reid (D-NV).
So, nuclear waste would continue to sit around nuclear power plants. Which means nobody is going to build anymore nuclear power plants in the U.S. ever. And since we'll be cutting back on carbon emissions, that will leave, uh, wind and solar power. And don't forget tidal power. Or maybe photosynthesizing bacteria.
Factor that into your long range economic growth projections, then see where the Dow should be.
