An Easy Case to Make

McCain and the Republicans are mocking Obama for advocating proper tire inflation. They're calling for tax breaks for oil companies and for giving them more federal land to drill on.

Why?

Because that's what they're being paid to do, with oil company campaign contributions. Mocking conservation, cutting corporate taxes and opening more federal land up to drilling all have one thing in common: they lead to higher profits for the oil companies.

It's not hard to understand. It's an easy case to make.
