Of course the study is right about the impact on congressional voting, especially in the more populous Midwestern states. Or for that matter Montana, which may not be that dirty but you may have to use a gallon of gas to just get to the store.

This is an argument for cap & trade, which won’t hit so hard in the big empty states’ gas tanks.
