All of the major candidates for the 2016 presidential election will have had samples of their DNA taken and analyzed (perhaps without the candidates’ permission.) The results of the analysis for each candidate will be widely disseminated and will influence many peoples' voting decisions - 70%

Within five years the Israeli economy will have been devastated because many believe there is a high probability that an atomic bomb will someday be used against Israel – 30%

Within ten years there will be another $200 billion+ Wall Street Bailout - 80%

I'd take the other side on any of these if we can find a way to make it precise.
