Los Angeles Times: “Welcome to the new frontier of campaign tech — a loosely regulated world in which simply downloading a weather app or game, connecting to Wi-Fi at a coffee shop or powering up a home router can allow a data broker to monitor your movements with ease, then compile the location information and sell it to a political candidate who can use it to surround you with messages.”
“Campaigns don’t match the names of voters with the personal information they scoop up — although that could be possible in many cases. Instead, they use the information to micro-target ads to appear on phones and other devices based on individual profiles that show where a voter goes, whether a gun range, a Whole Foods or a town hall debate over Medicare.”
