I am not concerned that they will do things which I merely don't like, I am concerned only that they may do something which constitutes an injury to me and mine. Pollution drifts across the border. At that point it becomes MY problem.
And at that point, your state can take that issue to federal court for resolution.

For a like reason, I made no reference to the "power to regulate commerce among the several States." I always foresaw that difficulties might be started in relation to that power which could not be fully explained without recurring to views of it, which, however just, might give birth to specious though unsound objections. Being in the same terms with the power over foreign commerce, the same extent, if taken literally, would belong to it. Yet it is very certain that it grew out of the abuse of the power by the importing States in taxing the non-importing, and was intended as a negative and preventive provision against injustice among the States themselves, rather than as a power to be used for the positive purposes of the General Government, in which alone, however, the remedial power could be lodged.
Do you want a Constitution that is an "enduring document", fixed as it was understood and intended by those who wrote and ratified it until such time as it is amended, or do you want a "living document" that can be molded into whatever meaning we can imagine, to suit whatever it is we want at the moment?
