Obama has come out in favor of closing the 'Enron loophole'. which limits regulation with respect to oil price speculation. This is a position that McCain agreed with in Y2K, when actually was a maverick. Closing this loophole is something that Keith Olbermann and Bill O'Reilly both agree on, so it will be interesting to see how the media reacts to this. This is a measure that can actually have an effect on oil prices.

Edit: this loophole was tacked on a 2000 bill by Phil Gramm, McCain's financial advisor.
