It really is simple. In light of his refusal to release tax returns before 2010 (and incomplete returns at that), with the legitimate concern that Mitt had or has one or more Swiss bank accounts, and with the realization that he considers the release of his pre-2010 tax returns non-negotiable, I think the controversy may be identified if a journalist (or even a reasonable facsimile) will just ask Mitt or his handlers the following question:
(proceed below the squiggle for the potential knock-out query)
The Question:
"Did Mitt, his wife Ann, or any trust which was owned or controlled by either of them, participate in the IRS Swiss bank account disclosure amnesty that concluded in 2009?"
If the answer to this question is "yes", it's game, set and match Obama.
