[Former Arkansas Gov. Mike] Huckabee told the AP that Republicans not paying attention to the personal lives of their own candidates "would be troubling because that inconsistency would show it really wasn't about principles. It was about personality, character assassination and politics."

Well, duh. You mean Newt Gingrich attacking Bill Clinton for having an affair, while he was doing the same thing, was character assassination, rather than a principled stand? Again, I say, duh.
