Just Call Him Oily John

Because McCain is totally, utterly, and completely in the pocket of Big Oil. The slick details can be found here.

BTW, McCain's campaign contributions from Big Oil really took off when he switched positions on off-shore drilling (which MIGHT yield 1% a day of our needs by 2020).  McCain's lips were applied to Big Oil's ass, and Big Oil's money started to grease old Johnny Boy's palms. 

Quite a trade.
