They are baiting Romney camp into demanding open records on obama’s citizenship credentials, passport, selective service, social security, Occidental College, Columbia U., Harvard records, and how he fared, how it was all paid for, etc.
As soon as he does some facsimile of that, they will then go into the secrecy of the Mormon Church — the ace up their sleeve (or some such place). That (IMHO) is the end game here. The “who’s got the most damning secret” angle.
My bet is the ace is up the other place.
