so you're saying he has a good reason for not saying anything?
politically - YES.
He will alienate either the hardcore neocons - and they're out there, whether they admit it or not - or he will alienate those tea party repubs who dislike the neocons greatly.
So by playing dumb... "I am no familiarrrrr with them" he can put this onion peeling process off a bit longer.
Mind you, he will have a better prepared answer next time he sees a microphone, bet on it. And idiots will say "See, that makes sense, he doesn't offend anyone". But cain knew that owning/disowning them woudl cost him votes.
Same way christie would be #1 on every poll... until voters discovered his liberal record was a lot like Mitt's.
So it's smart politics, but morally hypocritical since Cain can't stop patting himself on the back saying "be careful piers, you might just get the straight answer from a no-nonsense candidate like myself".
IMO, anyone who brags about their integrity, usually needs to work on it. Anyone who brags about how little they lie, is probably lying.
