Here is the story from Alabama: Cows pass gas.  No surprises there.  What is surprising is that democrats in Washington are now trying to pass a tax on the gas which is passed.  Only a liberal democrat could conceive of a passed gas tax.  Of course, as this story indicates, it is not called a passed gas tax; rather, the law has an environmentally friendly name so we can feel righteous by supporting it.  (But it still is what it is… a tax on gas passed by pigs and cows.)
