That opens to the door talking about his time as a mathematician for the Navy designing guidance systems for ballistic missles (rocket scientist), VP of corporate data systems for Pillsbury (computer guy), and chairman of KC Federal Reserve (banker).
I have an in law that is a local branch manager for a regional bank. When I mentioned Cain's time at the Fed, he suddenly got interested. When I explained Cain's entire background, his reply was "Wow, maybe I should give him a look."
If Cain get's tagged as the pizza guy, he'll be in trouble. If his entire life story gets out, he'll make it.
I agree. But for the reasons you stated, I think that by the time the general election comes around, Cain's credentials will be pretty well known, assuming his team does a good job getting them out there.
And I think Republican primary voters will get the message long before the primaries are over.
