Want to track political futures markets for 2008, but too lazy to click your mouse three times? Slate has the solution:
If a single prediction market is wiser than the pundits and the polls, imagine how wise all the prediction markets are together. That's the idea behind Slate's "Political Futures," which offers a comprehensive guide to all the big political prediction markets. From now until Election Day 2008, we'll publish regular updates of the key data from Iowa Electronic Markets, Intrade.com, and Casualobserver.net.
Arbitrage opportunities are sure to abound. Good luck.
