by Gabe BullardThree candidates for mayor of Louisville will debate Wednesday at the Venture Club's monthly luncheon.Program Chair Lynn Allen says Democrat Greg Fischer, Republican Hal Heiner and independent Jackie Green will discuss their plans for managing Louisville's entrepreneurial economy."We want to see the next mayor have a policy and a plan to encourage the growth of young companies in Louisville because this is where we believe most of the jobs will come from in the future," she says.This is the first debate with the three candidates since the May primary. Green was not invited to a forum last month, and was added to the Venture Club program Tuesday. Allen says Green's omission was an oversight.At least one other independent candidate, Nimbus Couzin, is running for mayor, but he has not actively campaigned.
