I believe Newt Gingrich (we should call him "The Grinch") and Rick Perry's attacks on Mitt Romney's years at Bain will backfire on them. They sound envious and desperate.
It's really sad when Republicans adopt class warfare like Obama. Most Americans love and appreciate the free market system. Bain is a company where private investors take risks with their own money, not government money, to create great companies and receive a return on their investment. Mitt and Bain have helped create outstanding businesses with hundreds of thousands of jobs, like Sports Authority, Staples, Domino's pizza, Brookstone, Sealy. etc.
We lived in Boston when Mitt was at Bain Capital. We had several friends that worked for Bain. They were encouraged and motivated to build companies and create more jobs! They were very pro-business and pro-growth.
Bain has a 3-to-1 ratio of creating successful businesses.
Obama's failed at being a venture capitalist, pumping billions of taxpayer dollars into companies like Solydra that was followed by bankruptcy and layoffs, Telsa Motors and FiskerAutomotives to build electric cars, and his intervention to help save Chrysler and GM. I can't wait to see what Mitt can do for America like he did in job-creating at Bain, turning around the Olympics when it was in financial ruins and scandals and getting Massachusetts out of debt. He's the only candidate who has the organization, money and experience in the private sector and government to beat Obama! Our country needs Mitt!
