Daily update

Sorry for no updates for a few days. I have been in Scotland and they don't have the internets over here quite so much. Anyway, I am now using both the democratic and the republican price in each market. That eliminates the bias of high prices to stay high while low prices rise. I had been overestimating Obama's chances by looking only at Democratic prices. But meanwhile, Obama has had a very strong week. I now show him as having an overall 86% chance, as he is dominating the simulations that result in close contests. The mean EV he wins is 291, same as the amount he is currently winning.

Cody, can you comment on Lance Fortnow's claim that state outcomes are highly correlated? http://weblog.fortnow.com/2008/09/markets-and-polls.html
