Recognizing that it is likely to be a close election in November, Team Obama is already dedicating significant resources to the battleground states. The New York Times' Michah Cohen reports:

Below is a chart of the Obama campaign’s field offices and paid staff in 12 states that are likely to prove decisive in November...[I]t is not clear how active each office is, and in a couple cases the number of offices reported by the Obama campaign differs from the number reported in news accounts, although by just a few offices.

Caveats aside, Mr. Obama has a substantial head start in organizing a general election get-out-the-vote operation, particularly in the number of field offices he has established.
