I think this comment over at The Oil Drum puts it well:
So, to summarize the current situation:
Refiners: "We are at our limit, can't use the sour crude, pushing off repairs and closing down production in anticipation of Rita"
OPEC: "Want more Heavy Sour Crude? Here's 2 mbd. Otherwise we are at our limit."
Nigeria: "We are in a civil war and cannot guarantee production."
Iraq: "We are in an insurgency/civil war and cannot guarantee production."
Iran: "We are going to leave OPEC and cut exports if you keep trying to block our Nuke plants"
Venzuela: "America is going to invade us for our oil"
Non-OPEC: "We are at our production limit"
Bush/Delay: "I'm worried that if we don't make the tax cuts permanent, the economy might falter"
American Public: "Cut the gas tax now"
Good summary, but you forgot one...
GM: Hey, everybody! Look at the new SUV's we're announcing! Shiny!
