One of Trump’s biggest “drill, baby, drill” initiatives suffered a huge setback as it was announced that a lease sale in Alaska’s Arctic National Wildlife Refuge ended without a single bidder. The sale, which was required by Congress, marks the second time in four years that an effort to auction oil and gas leases in the pristine wilderness — home to migrating caribou, polar bears, musk oxen, millions of birds and other wildlife — has been a flop. The repeated failures suggest that oil companies are either not interested in drilling in the refuge or do not think it’s worth the cost.
