Put your (virtual) money where your mouth is

PBS Frontline's presidentialmarket.org just got real interesting this week. They added Badnarik, of the Libertarians, and David Cobb, of the Green Party. (Nader hasn't met the 20-state ballot minimum to get listed.)

More interesting, however, is that you can bet (invest) on shares of whichever way you think a particular state will go - GOP, Dem, or other. You get a base amount to start investing, and candidates pay dividends when officially nominated by their party.
