Yesterday we explored John McCain’s flip flop on ethanol–first he opposed it and then supported it. Today, when he unveiled his environmental policy platform, Senator McCain again lacked consistency with past statements.

According to Reuters, McCain took “swings…[at] tariffs that protect domestic ethanol producers….Speaking to reporters following his remarks, McCain said he would let lapse a 54 cent-per-gallon tariff on ethanol imports which expires at the end of 2008.

According to the NYTimes’ blog, The Caucus, here is how McCain skirted around opposing ethanol.

“Here is how Mr. McCain – who is planning visits to Sioux City and Des Moines later this week – described the issue without using the E-word in his speech today on energy issues:

‘Alcohol fuels made from corn, sugar, switch grass and many other sources, fuel cells, biodiesel derived from waste products, natural gas, and other technologies are all promising and available alternatives to oil. I won’t support subsidizing every alternative, or tariffs that restrict the healthy competition that stimulates innovation and lower costs.

‘But I’ll encourage the development of infrastructure and market growth necessary for these products to compete, and let consumers choose the winners. I’ve never known an American entrepreneur worthy of the name who wouldn’t rather compete for sales than subsidies.’’’
