You're right. Congress is posturing, and a windfall on oil company's tax isn't going to reduce gasoline costs. Demos has an excellent assesment of why oil prices are so high, and a solution. Hint... its not congresses fault. Anyone who thinks it is, lacks a basic understanding of economics.
So what's your solution? What did congress do wrong? (and don't say "ethanol" like Skeppy, that was as much Bush's pet project, and he was in the news defending it within the last week) What should they be doing?
Or are you just identifying a problem, and blaming Democrats as a reflex?
