I would say the media is just as culpable here given how much influence they have on public opinion in America (and I would garner that's where most politicians get their information.) FB directly competes with most media publications for attention and content so they have a direct profit motive to target FB. The ironic part is that all the reporting is done under the guise of protecting or informing public privacy, but media publications continue to be amongst the worst offenders when it comes to user tracking and privacy violations. Of course, they'll never report on how they sell out your address, email, phone number, political views, etc. if you subscribe to their magazine because heaven forbid they hold themselves to some higher standard.
