Well the Senate has not much saying if someone abroad tells what to do or go down monetary.
As the decisions will affect the affection American products will have, the people in Europe for example are "enviromentally concious" and look for brands that are in the limelight in that aspect, therefore the American auto industry has never fared well abroad for example, Jimmy Carter tried to force them to go that way but look at the products the companies spit out, utter rubbish ???
Reagan didn´t harass them that much and look what came out then, good stuff in my book.
On the other hand personally I could live with the fact that gas would be like 10 bucks a gallon without any pollution fines for gross polluting cars I´d just use them more with thought.
