Minimum Markup Law

So Wisconsin has this nice little law that requires gas companies to inflate the price of gas by 9.18% from the price at the terminal. So that means deals like this from Woodman's had to be taken away. Oh yeah and when this guy tried to help us out by lower prices he got smacked around too.

So after the prsident of Badger Ethanol, a contributer to Gov. Doyle's campaign, has gone public with his want of the minimum markup law to be removed, Doyle says Don't Enforce Law on Ethanol Sales

In the article he says

This law was passed at a time that it was designed to protect the little guy against the bigger people. But it used to apply to every single product. Now it only applies to gasoline."

So why is Doyle only calling for the removal of the Markup only for Ethonal E-85? If it shouldn't apply to gasoline sales it should be across the board, right? Or is it the Petroleum industry hasn't given him enough money yet?
