There have been some very strange price movements in the 2008.DEM.VP.GORE contract on intrade since late May:
This contract pays $10 if Gore is the democratic vice-presidential candidate in 2008. The probability of this event has got to be approximately zero. I can't imagine why someone is sinking thousands of dollars into this contract.
This has to be either a crazy hunch by a very rich individual, or an attempt to profit from some astonishing inside information.
