Why do Republicans oppose Obama on offshore drilling?

Who would stand to gain from the offshore drilling, other than Americans, mostly Republicans. It would help if gas would come down to less than 2.00$ a gallon, then when they repeal NAFTA that slick sick Willie established, and our jobs came home, we could afford to go to work. The elected do not realize, with their big pay checks how just a few dollars more in cost, hurt the working man.
