Starting just past 6am, someone dumped about $100,000 worth of Obama shares to tank Obama's odds from 69% to 64% within a few minutes. Only 15 minutes later, Intrade's Obama odds had recovered to 68%. Throughout the day, the huge Obama dumps were repeated over and over, to the tune of about $2M. Can you buy Intrade odds? Apparently, yes. For $2M, you can reduce a candidate's odds from 69% to 66%. Did American Crossroads find this a good use of secret donor funds?"
