When the "evil" Bush and his oil company friends were in power, gas was less than $2 in the US, and all the liberals bitched and moaned about how high it was.

Change the question to how much the world price of oil can differ from the domestic price. Ans: very little.
Now discover a couple billion new barrels of oil and ask the same question. That's why Obama says we can't drill our way out!
People wake up and smell the coffee!
I don't care which branch of government it is Local, County,State, Federal....It's all Legalized Organized Crime. Try to stop it and see what happens to you.
