Mitt Romney doesn't discuss his private equity experience in much detail on the trail. That appears to be changing. The Republican presidential candidate is out with a Wall Street Journal op-ed that goes deep into his work at Bain and how it informs his worldview:

My business experience confirmed my belief in empowering people. For example, at Bain Capital we bought Accuride, a company that made truck rims and wheels, because we saw untapped potential there. We instituted performance bonuses for the management team, which had a dramatic impact. The managers made the plants more productive, and the company started growing, adding 300 jobs while Bain was involved. My faith in people, not government, is at the foundation of my plan to strengthen America's middle class.

Some of the anecdotes in the piece have appeared in Web ads or in campaign speeches, but not in such depth. The op-ed comes a day after Gawker published hundreds of Bain documents that contain new details on Romney's investments. 

If Romney does start incorporating Bain more into his campaign, it will be a relief for some Republicans.

He "doesn't know how to talk about it, which I don't understand," Republican pollster Frank Luntz lamented in July.

“Romney has achieved some remarkable things in life. Romney’s probably the last person to talk about them,” House Majority Whip Kevin McCarthy said earlier this month
