Electoral map from Pollster.com as of 10/25.

From Obama camp website:

From the beginning of the general election, strategically, we tried to have as wide of a map as possible. Our belief was we wanted to, on the morning of Nov. 4th, have as many possible avenues to as many electoral votes as possible. And we think we've been able to create that dynamic and have a lot of competitive states in play here. - David Plouffe
