Miller, who beat Murkowski in the August primary, used a candidate-to-candidate question during the Alaska Public Broadcasting debate to ask Democrat Scott McAdams to compare his experience as a local official to that of Murkowski's when she first took office.
McAdams served eight years as a school board member and mayor. Murkowski was a state legislator when her father appointed her to his long-held Senate seat when he was elected governor in 2002. Murkowski has criticized McAdams as too inexperienced for the job.
