Lower Gas Taxes Won’t Equal Lower Prices, Democrat Says
If Congress were to lower the 47 cents per gallon federal and state tax currently levied on gasoline, a price reduction would probably not be passed on to consumers, Sen. Ben Nelson (D-Neb.) told Cybercast News Service on Tuesday. But two Republicans said they think a tax cut would provide short-term relief.

So lets see if I have this right. Lower gas taxes won't lower the price of gas but raising them (ie., "windfall" gas tax) will. Brilliant. Simply brilliant. A sixth grader has a better handle on basic economics than they do.
