In January 2009, the month Obama took office, the average price of a gallon of regular gasoline in the US was $1.85
Obama made it clear from the beginning that his goal is higher energy rates. And he's followed through by shutting down both the Keystone Pipeline and offshore drilling.
Less Supply = Higher Prices, last time I checked. AND this is worse than just less supply. Oil prices are partially based on futures and speculation.
Thus President Obama signaling to the world that we have no intention of adding to the supply gives speculators reason to raise the price. It also affords our middle east oil suppliers (who love us so much) a chance to bend us further over the barrel.
Cut to today-
According to GasBuddy.com People are paying $5.89 for a gallon of regular gas at a Shell station in Lake Buena Vista, Florida.
LAUGHABLE UPDATE (2-22-12) - Obama doesn't accept responsibility for gas prices
