I am completely against decreasing fuel tax or releasing any fuel from the National Reserve.
Part of me LIKES having the prices as they are, maybe it will be enough to finally encourage us to get away from an oil based economy a find alternative sources.
We should of woke up during the 70s gas shortage, but instead we are driving SUVs, some of which only get 10-15 miles per gallon (and some, amazingly less).
All of the above said, they should eliminate all the tax on all distillate fuels (diesel and heating oil). This way, the price of goods does not 'trickle down' to show the increased costs for fuel truckers are paying, it would allow the price of goods to remain constant and encourage the economy to grow.
Heating oil is also a distillate fuel and should not be taxed at this time, or only taxed after a certain number of gallons per year, for obvious reasons.
