Three Big Questions About Obama's Massive Voter Database

This article is from the archive of our partner .

President Obama's re-election campaign is reportedly building a massive database of information about potential supporters.

The database seems to bring together information about supporters gathered from all branches of the campaign -- everything from an individual's donation records to volunteer activity to online interactions with the campaign -- aimed at allowing the campaign to personalize every interaction with potential supporters.

Earlier this month, we built an interactive graphic showing how different Obama supporters received different variations of the same email -- one way that the campaign may be using data to personalize messages.

The reason we can't speak with certainty about the campaign's database is because Obama's campaign won't talk about it. Citing concerns about letting Republicans learn their tactics, the Obama campaign declined our request for comment -- just as they have with other outlets -- about what data the campaign collects and what they're doing with it. The campaign did emphasize to us that, regardless of what information they gather, it has never sold voter data or shared its voter database with other candidates.

Here's a guide to what we know -- and what we don't -- about the information Obama is collecting about voters.

1. What information is the campaign collecting about individual supporters?

We only know some of the data they're collecting -- but they're clearly collecting a lot.

The Obama campaign has hired a corporate data mining expert, Rayid Ghani, to serve as the campaign's "chief scientist." Ghani has previously researched how to use a retailer's record of customer purchases to predict what a particular customer will buy during a given shopping trip -- the same kind of data crunching that Target has apparently used to predict whether shoppers are pregnant. The campaign is continuing to hire "analytics engineers" and other data experts.

Some of the most important data campaigns need is already public. State voter files include the names and addresses of individual voters and their voting history. Campaigns don't know who you voted for. But they know when you voted, when you didn't, and in some states, your race and party registration.

The Obama campaign website asks supporters for basic information, starting with your email address and ZIP code. If you sign up for an account on the site or register as a volunteer, you may also be asked for your mailing address, phone number, and occupation.

But the campaign's privacy policy says the campaign has the right to gather far more: from information about how you use the campaign website, like what you click on and which pages you view, to data about how you interact with campaign emails, to personal information you submit as part of blog comments, interactive forums, or contests and games on the campaign's websites.

Logging into BarackObama.com using Facebook gives the campaign permission to access your name, profile picture, gender, networks, list of friends, and any other information you have made public.

How much of that information are they tracking and connecting back to you? The campaign won't give an overarching answer to that.

That doesn't mean they're tracking everything. For instance, the campaign website currently features an interactive graphic that allows users to see how healthcare reform law might benefit them. To do so, users click through several options, selecting whether they have private health insurance, Medicare, Medicaid, or no insurance at all, how many people are in their family, and what their annual household income is.

According to the campaign's privacy policy, the campaign may track how individual users interact with the campaign website. But the campaign said that none of the information entered into the health care interactive was linked back to individual supporters.

It's worth noting that, just like many websites, the campaign also works with third party ad vendors who use web cookies to track your browsing across the Internet. This enables them to serve you ads on different sites -- and to target their ads based on the sites you visit.

2. What will happen to all this personal information once the campaign is over?

It's hard to know.

The campaign's privacy policy reserves the right to share the personal information it collects "with candidates, organizations, groups or causes that we believe have similar political viewpoints, principles or objectives."

The campaign wouldn't comment about any future plans but said its track record demonstrated its approach to privacy protection.

After the 2008 election, Obama's list of 13 million email addresses was not given to other candidates or used by the White House. Obama launched "Organizing for America," a Democratic National Committee outreach program that drew on Obama's wide network of supporters to generate support for the president's agenda.

"This campaign has always and will continue to be an organization that respects and takes care to protect information that people share with us," spokeswoman Katie Hogan said.

But the privacy policy shows the campaign is reserving the right to share their increasingly rich database. And some experts are wondering what Obama will do with it once the campaign is over.

"As a voter, I would feel a lot more comfortable if campaigns gave voters the option of whether or not they could pass their information on to other groups," said Andrew Raisej, founder of Personal Democracy Forum and TechPresident, a site focused on the ways technology affects politics.

From a voter's perspective, "the fact that I gave the Obama campaign $10 for six months, or emailed the campaign 10 times, may not be information that I want anyone else to know," Raisej said.

Lillie Coney, associate director of the Electronic Privacy Information Center, said she's "never heard anyone complain" about Obama's 2008 campaign giving their personal information away.

"The success of the Obama campaign in 2008 in getting millions of people to log onto their website to give personal information and volunteer and do all sorts of things for the campaign hinged on trust," she said. "People did not believe that that information was going to go anywhere."

Any choice to share supporters' information should take their preferences into account, Coney said. A campaign could easily create a checklist of politicians and organizations, allowing users to grant permission to share with some groups and not with others.

3. Is there any way to erase yourself from the campaign's database?

As far as we can tell, no.

President Obama's "Consumer Privacy Bill of Rights," released last month, says that consumers' right to control their own personal data "includes a right to withdraw consent to use personal data that the company controls."

The Obama campaign does make it easy to unsubscribe from email, text messages, or newsletters from the campaign. But we couldn't find any way to unsubscribe yourself from their database -- and the campaign wouldn't comment. There's also no apparent way to see what information the campaign is storing about you.

In a report on consumer privacy released yesterday, the Federal Trade Commission (FTC) also called on companies to "provide consumers access to the data collected about them."

Both the "Consumer Privacy Bill of Rights" and the FTC's report are meant to serve as guidelines for future legislation regulating companies' use of consumer data. How exactly any laws will apply to political campaigns isn't clear.

A White House official said that the Privacy Bill of Rights "applies to how businesses handle consumers' personal data online, and will impact all organizations using personal information collected through commercial means," including campaigns.

Obama's privacy policy notes that users, just as they can at any website, can disable cookies if they don't want their browsing tracked. And to the campaign's credit, EPIC's Lillie Coney said, the privacy policy also includes a link to the Network Advertising Initiative, which allows users to control which digital advertisers are tracking them.

More comfortable online than out partying, post-Millennials are safer, physically, than adolescents have ever been. But they’re on the brink of a mental-health crisis.

One day last summer, around noon, I called Athena, a 13-year-old who lives in Houston, Texas. She answered her phone—she’s had an iPhone since she was 11—sounding as if she’d just woken up. We chatted about her favorite songs and TV shows, and I asked her what she likes to do with her friends. “We go to the mall,” she said. “Do your parents drop you off?,” I asked, recalling my own middle-school days, in the 1980s, when I’d enjoy a few parent-free hours shopping with my friends. “No—I go with my family,” she replied. “We’ll go with my mom and brothers and walk a little behind them. I just have to tell my mom where we’re going. I have to check in every hour or every 30 minutes.”

Those mall trips are infrequent—about once a month. More often, Athena and her friends spend time together on their phones, unchaperoned. Unlike the teens of my generation, who might have spent an evening tying up the family landline with gossip, they talk on Snapchat, the smartphone app that allows users to send pictures and videos that quickly disappear. They make sure to keep up their Snapstreaks, which show how many days in a row they have Snapchatted with each other. Sometimes they save screenshots of particularly ridiculous pictures of friends. “It’s good blackmail,” Athena said. (Because she’s a minor, I’m not using her real name.) She told me she’d spent most of the summer hanging out alone in her room with her phone. That’s just the way her generation is, she said. “We didn’t have a choice to know any life without iPads or iPhones. I think we like our phones more than we like actual people.”
