What Donald Trump and Hillary Clinton are doing to drive the vote in Georgia

While the drama of the 2016 campaign plays out on television, news sites and social media, the real work is in call centers, computer servers and neighborhoods where volunteers knock on doors and work on phone banks to make personal contact with voters.

It’s a high-tech mission where campaigns carefully craft messages that can be personalized for individual voters based on the enormous amount of data they collect. Campaigns know your name, address and voting history from databases purchased from the state. In many cases they know your phone number and email address.

Did you choose a Democratic or Republican ballot in a primary? That’s a big clue mined from the state’s voter rolls.
