In a recent post, Ramesh noted that the Romney campaign is optimistic about the Obama campaign’s lack of focus:

The operatives believe the Obama campaign is unfocused, to its own detriment. They are looking at graphs and charts of what the Obama campaign is doing in various media markets. In most of them Team Obama is running multiple ads with different messages — a fact they interpret as the campaign’s having difficulty adjusting to a more competitive race than it had expected. The Romney campaign’s message discipline was contrasted to this cacophony.

This apparent lack of focus is presumably a reflection of the Obama campaign’s close collaboration with the Analyst Institute, an organization dedicated to bringing test-and-learn strategies to politics. That is, Team Obama is running multiple ads with different messages to determine which messages are most effective with which constituencies, and in doing so they are demonstrating that they anticipate an extremely close election in which moving the needle with, say, rural independent women in Missouri in the most cost-effective manner will make the difference between victory and defeat.
