Senator Norm Coleman stuck with a campaign promise today (Weds)and voted against allowing oil drilling in Alaska's Arctic National Wildlife Refuge. President Bush has argued that ANWR's oil - anywhere from 5.6 billion to 16 billion barrels - should be tapped to reduce America's dependence on foreign crude. Environmentalists say that the wildlife refuge should be preserved as a sanctuary for polar bears, musk oxen, caribou, and migratory birds. Coleman was one of only eight Republicans who voted against the drilling. He said he might have supported the plan if it placed more emphasis on bio-diesel.
