Manipulating the Market to Swing an Election 

InTrade was an online prediction market, where traders could bet on the outcomes of future events. It has often been studied by statisticians, as it may offer more accurate results than opinion polls, since real money is on the line.

A new study indicates that back in 2012, one trader lost millions in what was likely an unsuccessful attempt to make it appear Mitt Romney was faring better than he actually was. Amazing.
