John McCain's camp is obviously trying to lay the groundwork for independent and moderate voters. Why else spend money on an ad about the environment. There's no way he'll get to the left of Hillary Clinton or Barack Obama on this issue, but the good news is a) he doesn't have to and b) George W. Bush and the current crop of Republicans have left him a million miles of room between the right and the center. In the below ad he frames climate change as something that has to be addresses as both an environmental issue and a national security issue. He also gets a jab in at the regulation-happy Dems. He loses points, though, for another visually awful ad, what with the high-speed effects.
