Moving Hillsborough Forward, the nonprofit formed to promote the proposed 1 cent transportation tax, has launched a new television ad. This one focuses on jobs, saying that the tax will create 25,000 of them. "We think that's a conservative estimate," said David Singer, an attorney with Holland & Knight working on the campaign. "These are across the board jobs. Anything from contractors, engineers, construction, maintenance, operations, drivers, technicians, administrative and customer service staff." He described them all as long-term sustainable jobs, pointing out that even construction jobs affiliated with light rail will be available for 30 years, because that's how long it's expected to complete the system. Singer notes that a lot of candidates on the campaign trail talk about job creation in vague way.  "This is a concrete plan that will bring jobs here quickly," he said. "We're excited about it."
