On the effect of unregulated trading (speculation) on oil prices.  It creates demand nearly equal to the demand China has in oil markets.  Hmmm, wonder if that raises prices?  

We may never know, the Enron loophole didn't take hold in the news cycle.  Barack tried it in a few speeches, but I guess it is too hard for people to grasp.

They like to bend over and get bushed at the gas pump.  Well, to each, their own.
