Sorry to pee on the premise of Clint's story, but Mitt Romney hasn't had anything to do with Bain Capital since 1998, when he left to head up the Salt Lake City Winter Olympics. You may or may not be horrified to hear that the firm's current leadership group are mostly Democrats.
As far as changes to D&M's business model go, they're likely to be evolutionary. For one thing, they were already owned by another investment group, who managed to put them on a growth trajectory attractive enough for Bain to pay a high multiple. For another, Bain is known for focusing on portfolio management -- running the companies that they own well -- rather than on pure financial engineering to generate returns.
