Democrats amass a huge voter database

The Obama campaign amassed a vast database about voters, which gave it a technological edge over the Romney effort. The database includes voter history and political donations, supported by large amounts of publicly available consumer data. It was augmented by data collected through its mobile apps, which include permissions that allow it to collect information such as friend lists and interactions.

Some of the data gathered by the Democrats during the recent presidential campaign.
