There has been a bit of chatter about this in recent weeks, esp. on Max Keiser. Basically, the Nadex is now going to be used as a futures market for betting on the outcomes of the US political process. And various possible scenarios have been suggested by Max; eg. 1) huge amounts of money bet by the "too big to fail" on one candidate, yet he does not win. However, a loss would cause catastrophic fallout in the financial markets (due to the big bets failing), therefore the genuine winner must step aside in favour of the other. 2) the "paper price" of candidate "A" (eg. Mitt Romney) is much much higher than the actual number of physical votes cast in his favour, etc. http://online.wsj.com/article/BT-CO-20111221-709555.html http://rt.com/programs/keiser-report/episode-236-keiser-report/
