Suddenly Democrats Care About Privacy?

Throughout the West, most people have given up on the hope that they might have any privacy at all. They know that their phones are listening and tracking devices, some even buy listening devices for each room in exchange for access to information at their request, and we're monitored by CCTV hundreds of times an hour. Democrats and Republicans alike ignored every intrusion into privacy. Now, suddenly, Democrats care about privacy. Any guesses on what got them to shift?
