The reliably contemptible "Powerline" blog carried a brief description of Orca on Monday. Emphasis added, because I'm feeling helpful:
The Democrats like to think that their “ground game” is the tie-breaker that will give them the edge in a tight election, but this year there is reason to believe that the Democrats’ efforts will be equaled, if not exceeded, by those of the Romney campaign. The Romney campaign is not only well-funded, but is run by one of the best organizers and managers of his generation, the candidate himself. Whom would you count on to organize anything, Mitt Romney or David Axelrod?
