I know this sounds dumb, but what is Intrade and why is a high number important to Gov. Walker? :)
Intrade is an online Prediction Marketplace. People bet on current events. Intrade is uncannily accurate because people "in the know" tend to put money on certain events happening in the future.
Intrade is a place that trades stock in predicted outcomes...a sort of gambling. The price of a “share’ of Walker winning costs much more than one of him losing at this point...because those gambling on this market perceive that he is much more likely to win.
