Here's an excerpt from a discussion with an Obama campaign manager:
In describing the ground game, the official told of a conversation he had with a top field director on Monday. The GOP had tweeted that they had knocked on 75,000 doors in Ohio the day prior. Not to worry, the [Obama] director said, 'we knocked on 376,000.'
"Then the president came in, and this aide said, 'Tell him the door thing.' So he did. And the president responded, 'That's my team.'"
