1. Trump should double or triple his offer, that will give the story more life and get folks thinking. He should keep raising his offer every 2 days, until election day.

2. There should be a Trust fund opened up where folks can additionally contribute to the amount offered, that will become an unavoidable public metric for continuing attention on the offer, and a quantifier to guage public interest and demand in Obama providing the documents.

Can you imagine if the amount reached $30M or $40M or more ? It would be extremely uncomfortable for the President, and create lots of additional new voter suspicion by his avoidance if he didn't meet the challenge; afterall, he has nothing to hide, and it's for charity.
