Here is the current projection with "swing" states uncluded. As the website states, the brown line shows the number of electoral votes required to win the election.
And now here is the graph without the current 11 "swing" states included. The website considers a "swing" state a state where one candidate has less than a 5% lead over the other in polls.
What this shows us (other than how astonishing the gap is) is that Obama only needs to win over 1 or 2 of the swing states to have enough electoral votes to win. McCain needs to win all 11 to have a chance. I will be keeping up with this site until November, and I suggest you do as well.
