Former acting Mayor Kirk Caldwell is expected to formally announce Thursday his bid for mayor, challenging incumbent Peter Carlisle.
Caldwell served as acting mayor from July 19 to Oct.11, 2010, gaining the position when Mufi Hannemann resigned to campaign for governor.
Carlisle beat Caldwell in a special election in September 2010 to fill the final two years of Hannemann's term.
