Not that I would ever vote for him, but McCain made a very important point in the economic debate on Tuesday.
As one of the main things I hope for with the Paul candidacy is that he will bring isues to the floor that no one else will touch (e.g. the Federal Reserve), I must give credit when someone else brings up a point that no one else wants to explain.
In the debate, when McCain talked about ethanol bio-fuel, he said the magic word that needs to be said whenever anyone wants to seriously think about ethanol as a supplement to our energy supply.
Any realistic attempt to get any benefit from ethanol bio-fuel will almost certainly require us to use sugarcane-based ethanol - which will almost certainly have to be imported. Corn is simply to inefficient.
That is all.
