The irony of Trump's offer is that Obama's continuing refusal to release any of his records may cause a psychological dissonance in people who voted for him the first time around and don't want to know if they were taken in by a fraudulent misrepresentation of his background. This is a common reaction by those who have been swindled financially. As a result, they may be inclined to vote again for Obama just to keep any bad news from surfacing, or (hopefully) just stay home on election day.
