Obama and his Democrat friends were trying to tie the Bain 'outsourcing' around his neck, and Romney simply pointed out that any of the business decisions made while he was away running the Olympics weren't made by him, whether they were for good or ill. His name was still on the SEC documents, because, legally, he WAS still the CEO, because there hadn't been time to find a replacement before he had to leave for the Olympics. He didn't go back to head up Bain, because he decided to go into politics here in MA, so they got a new CEO. I don't see anything nefarious there.
Well, guess he saw that as valid criticism, because he’s definitely running away from his ownership of Bain. He “washed his hands” of Bain.
