"Knowles, 61, and Murkowski, 47, are two of the biggest political names in Alaska. Knowles served as mayor of Anchorage for six years in the 1980s and was governor from 1995 to 2003. Murkowski served in the Legislature for four years before being appointed by her father, Gov. Frank Murkowski, to the Senate seat he vacated when he was elected governor in 2002."
