Iraq produces around 3.2 million barrels of oil a day. Worldwide demand is around 92 million barrels a day. The spare capacity to make up 3.2 million barrels a day of lost production simply doesn't exist; pipelines and refineries in Iraq have already been targets of insurgent attacks, which causes production and supply disruption. The margins between production and consumption are thin enough that even a third of Iraqi capacity being offline for any period would cause significant short-term spikes. But understanding the economics and supply and demand issues around oil is apparently hard; blaming higher fuel prices on "speculators" when you're considering running for president is easy, I suppose.

to global oil glut.

No US oil is exported; very little Iraqi oil is imported to the US. Oil is priced on a global market. Therefore supply disruptions drive up prices globally. And if you actually read that link? it says this one analyst is "making a contrarian forecast", which actually means that no glut is forecast.

268K barrels a day of exports, with 9.2 MILLION barrels a day of imports? 9.2M - 268K = ? (Hint: the answer is nine million, give or take.)

believe that big oil is not ripping off consumers? Do you really believe that big oil deals with us honestly? That wall street speculators really have what's best for us at heart?

With demand at around 92 million barrels a day and supply not much more than that, with demand growth outstripping supply growth, and with oil companies scrabbling for shale and deepwater and other economically marginal resources? There's no reason to suspect that "speculation" has much of anything to do with oil prices, and plenty of reason to think that anyone who claims otherwise is economically ignorant.

Those poor people! Never knowing from one barrel-shaking event to the next - if they're gonna be able to feed their kids next week. Uh-huh. And the XL pipeline is gonna whisk us back to buck-a-gallon gasoline.

Is there some risk factor driving up prices due to events in Iraq? Sure. Is that what's behind the fundamental price of oil? No, it isn't. And cheap oil is never coming back, Keystone XL or not (tar sands oil requires a floor price of around $80 a barrel to be economically viable; the break-even point on shale oil is about the same).

I obviously forgot the sarcasm smiley.

This is very basic economics. No conspiracy required.
