So, Cain still said he’d personally serve as veep to Romney, and we can leave out “if the stars are aligned.” Cain apparently does not believe the LDS will turn Mitt against him, or for that matter against any wise policy.
Romney won’t pick Cain as his VP, for a myraid of reasons, the only benefit it would have is so Mitt could say he isn’t ‘racist’ when the media starts pointing out all the racist comments and history of the LDS church.
However, Mitt would lose some LDS support because there are a lot of older LDS who still believe blacks have the curse of Cain (no pun intended).
