In his final term in office Moore played a critical impact in the 1992 Alberta Progressive Conservative Leadership election. He is most famously known for delivering critical rural support of 35 Members of the Legislative Assembly of Alberta to help Ralph Klein win the Progressive Conservative leadership against Nancy Betkowski. Moore forced Ralph Klein and Rod Love to promote a fiscally conservative platform to renew the party in the face of deficit budgets and free spending scandals brought on by the leadership of former premier Don Getty. He retired from public office at dissolution of the Legislative Assembly in 1993.
