Technically this is more correct:
This map nails it. The Republican strategy for this election is the following:
First, win all McCain states (defending all that are in peril – e.g. Arizona)
Then, win the three reliable Bush states – Indiana, North Carolina, Virginia
Then, win the two Republican leaning swing states – Florida and Ohio
This completes the green states – must win states for Romney.
Then, win one other state – any of the yellow states.
Obviously, Romney will only compete in the green and some of the yellow states.
