Once again, for the utterly ignorant amongst us: the three biggest coal producing States are (in order) Wyoming, West Virginia and Kentucky. Pennsylvania and Illinois are a very distant fourth and fifth.
Wyoming, West Virginia and Kentucky all voted strongly for McCain/Palin and Romney/Ryan.
So now you know.
You're welcome.
Those would be the producers. Who are the consumers? States that have a large number of coal fired power plants?, etc.?
