Article 1, Legislative Brnch, Section 8, Clause 1
"The Congress shall have power yo lay and collect taxes"

       To clean up the six million gallons of crude oil from the gulf oil spill, Congress has decided to raise the current 8-cent-a-barrel tax on oil to 32 cents a barrel. The increase is supposed to raise nearly $11 billion over the next ten years.
       This demostrates Aritcle I, Section 8, Clause 1, because it shows the Congress's right to lay and collect taxes on oil, which is what it is doing so that the Gulf oil spill can be paid for. Obama and congressional leaders say that BP will be responsible for paying for the cleanup, and Senate Majority Leader, Harry Reid, says that "taxpayers will not pick up the tab."
       However  I feel that the price for gas will go  up at BP gas stations, which means the people will be paying for it. When people realize that BP's gas cost more and the fact that many people are upset with BP, some people will stop buying their gas. My question is, will this tax raise actually raise $11 billion?
