FILE - In this Nov. 14, 2008, file photo, former Alaska governors Bill Sheffield, left, Walter J. Hickel, Frank Murkowski, Tony Knowles, Steve Cowper, and Keith Miller, right, with then Gov. Sarah Palin, front left, and Territorial Gov. Mike Stepovich, front right, talk as they wait for a ceremony to honor Alaska governors as part of Alaska's 50th anniversary in Anchorage, Alaska. Bill Walker became the 13th governor of Alaska this week. Or its 11th governor. Or 16th or 17th. It depends on how you count. As it turns out, the state of Alaska doesn’t appear to have an official way of counting governors and their terms. (AP Photo/Al Grillo, File)
