Sasha Issenberg reports on Project Narwhal, the Obama campaign's attempt to "link once completely separate repositories of information so that every fact gathered about a voter is available to every arm of the campaign":
No longer will canvassers be dispatched to knock on the doors of people who have already volunteered to support Obama. And if a donor has given the maximum $2,500 in permitted contributions, emails will stop hitting him up for money and start asking him to volunteer instead. Those familiar with Narwhal’s development say the completion of such a technical infrastructure would also be a gift to future Democratic candidates who have struggled to organize political data that has been often arbitrarily siloed depending on which software vendor had primacy at a given moment.
