Presidential campaigns attract people who want jobs, especially people who worked in an earlier administration and want back in the game. Once Mitt Romney was the likely Republican nominee, he was surrounded by former officials from Bush 41 and 43 administrations, both pragmatists like Bob Zoellick and neocons like John Bolton. Romney has sung from both hymnbooks in recent months, but now the campaign is putting out the word that it wants to put daylight between Romney and the neocons.
It might be true. It's certainly a useful line to put out when those advisers seem trigger happy, eager to get America into another war or two, and the public doesn't want to hear it.
