Well it turns out that you can't take the Mac train since he's spent years as a passionate opponent of Amtrak. That's just one piece of the larger, somewhat odd, McCain puzzle on climate change. He's adopted a cap-and-trade proposal, but not really one that's far-reaching enough according to most scientists. And he doesn't flesh out his vision of a low carbon America very much -- there's nothing about increased transit ridership or any other explanation of how emissions will be reduced. Nothing, that is, except a love of nuclear power.
All told, it looks a bit like what you might come up with if you decided you wanted to break with your party on the sexy issue of global warming, but do it in a distinctly conservative way, and then decided that having gamed out the optics you don't need to think any further about the substance.
