At this point in time we have no clear picture of how the Iranian situation will end up but one thing is for certain– we in the US will remain dependent on oil for our transportation needs. If the public doesn’t like high gasoline prices, they would like them a lot less if we took ethanol out of the system. If supply is tight now, try taking another 10% out. Given that, if we didn’t have a Congress and Administration compromised by oil industry influence, a logical step would be to put more of a lower cost, domestic, high-octane product in the mix, not work to keep it out.
