Reporting from St. Petersburg, Fla. For weeks, Mitt Romney has gotten off scot-free in Florida because his cash-starved GOP rivals lack the financial resources to attack him on TV. Now a Democratic labor union is about to fill the void, attacking Romney's business record in a new ad, accusing him of what it calls "corporate greed" and linking him to Medicare fraud at a company where he once sat on the board of directors (see video below). AFSCME has purchased airtime in Florida for the 30-second spot, which bends the facts to link Romney to Florida's Republican Gov. Rick Scott, another businessman-turned-politician who once ran a company that paid $1.7 billion in fines, penalties and damages for Medicare fraud (still a record). In the anti-Romney ad, which begins airing Saturday, the male voiceover says that while Romney was a director of Damon Corp., a medical testing company acquired by Bain Capital in 1989, "the company was defrauding Medicare of millions." The ad goes on to point out that Romney profited handsomely from his investment in the suburban Boston company (which Bain, the private-equity firm Romney co-founded, sold several years later).
