Agreed. Democracy doesn’t work when you can send different messages to different people, and pretend that your platform is specialized to each case. Big data targeting helps them do this, but even regional targeting is probably fine.

I should know if you’re telling ____ he can have X before I vote for you to represent me.

That being said, so many people are adverse to critical thinking (on both sides of the American political split) that this feels like a non issue to begin with. So whatever.
