Cruz app data collection helps campaign read minds of voters
WASHINGTON — Protecting the privacy of law-abiding citizens from the government is a pillar of Ted Cruz’s Republican presidential candidacy, but his campaign is testing the limits of siphoning personal data from supporters.
His “Cruz Crew” mobile app is designed to gather detailed information from its users’ phones — tracking their physical movements and mining the names and contact in- formation for friends who might want nothing to do with his campaign.
That information and more is then fed into a vast database containing details about nearly every adult in the United States to build psychological profiles that target individual voters with uncanny accuracy.
Cruz’s sophisticated analytics operation was heralded as key to his victory in Iowa earlier this month — the first proof, his campaign said, that the system has the potential to power him to the nomination.
After finishing a distant third in New Hampshire, Cruz is looking to boost the turnout of likely supporters in South Carolina and in Southern states with primaries on March 1, where voters are more conservative.
The son of mathematicians and data process- ing programmers, Cruz is keenly and personally interested in the work.
“Analytics gives the campaign a roadmap for everything we do,” said Chris Wilson, data and digital director. “He has an acute understanding of our work and continually pushes me on it.”
Data-mining to help candidates win elections has been increasing among both Republicans and Democrats. Mobile apps by other presidential campaigns also collect some information about users.
But the Associated Press found the Cruz campaign’s app — downloaded to more than 61,000 devices so far — goes furthest to glean personal data.
The Cruz app prompts supporters to register using their Facebook logins, giving the campaign access to personal information such as name, age range, gender, location and photograph, plus lists of friends and relatives. Those without a Facebook account must either provide an email address or phone number to use the app.
Ohio Gov. John Kasich’s campaign app doesn’t request personal information from supporters, but it repeatedly nags users to let the campaign track their movements.
Democratic Sen. Bernie Sanders’ app, “Field the Bern,” requires supporters to sign in using their Facebook account or an email address, and it also repeatedly asks to let the campaign track their movements until they answer yes.
The other 2016 presidential contenders, including Donald Trump and Hillary Clinton, appear not to have officially sanctioned campaign apps.
The Cruz app separately urges users to let it download their phone contacts, giving the campaign a trove of phone numbers and personal email addresses.
