Mitt Romney's been getting hammered for his time as the head of Bain Capital for months, and he's sick and tired and not taking it anymore. It prepared him for the Presidency, he says, and he's making his case in a new Wall Street Journal editorial.

Romney makes the case in his new 'What I Learned at Bain Capital' editorial, debuting sort-of hilariously on the same day as Gawker's big Bain docu-dump that no one was able to understand, unless you're a financial reporter. The office supply company Staples, a Bain baby, gets a big endorsement  in the first paragraph. "The back-to-school season is here, and as parents take their children to shop for school supplies, I suspect that many of them will be visiting a Staples store," he writes. "I'm very familiar with those stores because Staples is one of many businesses we helped create and expand at Bain Capital, a firm that my colleagues and I built," he writes, taking off on the quickly-becoming-stale campaign line. 

He learned so much building businesses at Bain that he's already applied those lessons to the only two jobs he's held since, and he's prepared to make it a third:

The lessons I learned over my 15 years at Bain Capital were valuable in helping me turn around the 2002 Winter Olympics in Salt Lake City. They also helped me as governor of Massachusetts to turn a budget deficit into a surplus and reduce our unemployment rate to 4.7%. The lessons from that time would help me as president to fix our economy, create jobs and get things done in Washington.

This is the fleshed out version of the Bain defense the Romney campaign's been using after every attack ad and Bain controversy for months. He explains, using Bain anecdotes, how he plans to turn the economy around, spike American innovation, and save the middle class. Things are bad, he explains, but "I know what it takes to turn around difficult situations."
