A second Republican has entered the Louisville mayor's race.Metro Councilman Hal Heiner officially unveiled his candidacy with an announcement on the waterfront Tuesday morning. Heiner spoke to a crowd of Republicans and local supporters and said one of his first actions as mayor if elected will be to open the city's books for review."During the first four years, I will call for a full state audit of every department. A bi-partisan committee…commission will be set up to review the results of that audit and create an action plan and reverse the scandals of late. No area of government will be exempt from the audit. This will provide a fresh start for a government that has gotten dangerously off track," he said. "We have all read about the government financial scandals and secret deals giving away tens of millions of dollars to out of town developers without public input and without public knowledge. How can anyone trust a government operated in this manner? These government actions must come to an immediate end."Heiner is a civil engineer and businessman who has created two commercial parks, one of which is in Indiana.He is the second Republican to enter the race, following developer Chris Thieneman. Metro Council President David Tandy, Councilman Jim King, businessman Greg Fischer, 8664 co-founder Tyler Allen and west Louisville resident Connie Marshall are all running as Democrats. Professor and coffee shop owner Nimbus Couzin is running as an independent. Mayor Jerry Abramson is seeking the Lieutenant Governor's post.
