The anti-Bain propaganda did not work when Romney got elected governor...maybe they didn’t use it. The economy was better back then. In these depressed times with OWS out there, the anti-Bain charges will stick better. When used by Obama against Romney
Well, even if they used it, he might have been able to counter it, and like you say the politics of the economy back then would have been very different from today.
Even if the majority of Bain capital's companies came out better, if there are some which make Romney look like Gordon Grekco, then I have real doubts that he can defeat Obama. Plus his defense today just equated what Obama did with GM. That means Obamanomics = Romneynomics. It's already over.
