WASHINGTON (AP) — President Barack Obama waded into a decades-long fight over drilling in the Arctic National Wildlife Refuge over the weekend, announcing that his administration would pursue a wilderness designation for 12.28 million acres, barring drilling in most of the South Carolina-sized refuge. Alaska Sen. Lisa Murkowski, chair of the Senate Energy committee, said the administration's plans were a "kick to the gut" that treated Alaska as if it were a "snow globe out there" that should be left untouched. Even if the Arctic National Wildlife Refuge were opened to drilling, its known reserves are equal to about three years' worth of U.S.
