Roger, you are leaping to conclusions on an Obama position on coal based upon a hacked-up, taken out of context, video, which was pasted together by someone trying to whip up hysteria in a couple of swing states out of desperation. As I said, McCain's position is very similar, or at least it was a few weeks ago.
And no, the auto industry was not happy long after the Federal mandates on emissions and CAFE were imposed, and they still talked of doom and gloom. They were not happy when President George W. Bush signed into law a bill, which recently upped the ante on the CAFE standards.
You're much smarter than that, and you're not CDC.
