Do you remember the "Caveman Lawyer" skits from Saturday Night Live back in the 90's? Phil Hartman was the caveman lawyer and he won because he would always say "Well I'm just a caveman and I don't understand all your advanced ways" but that was the joke, he did understand it was the fact he was a caveman that gave him cover.
Cain uses this too only it's "I'm just a pizza guy so I don't understand all your strange Washington/Media ways so I might have screwed up", but he does understand because he was a lobbyist for 3 years, one of Dole/Kemp top advisers a losing Senatorial candidate and a losing Presidential candidate and he sits on several corporate boards and he had his own political talk radio show.
