That's quite an interesting map. The gray states ("no polls available") all look like safe for Bush to me. Of the green states ("too close to call") all were for Bush in 2000, except for California. Interestingly, the number of EVs in Cali is almost exactly equal to the number of EVs in the vulnerable Bush states (55 for Cali vs. 59 for the other five).
If Cali really is too close to call, and if each candidate wins the states where he is currently leading, this suggests an interesting strategy: Pour a lot of resources into Cali. If you win, then Kerry has to run the table in the Bush 2000 states that are marked as "too close to call". If he misses even one of them, he loses the election.
