re: If they do this to our food, and they do this to our water

Donald said "they" (the people who control political power) "rig the media, they can wield absolute power over your life, your economy and your country, and benefit big-time by it". Donald also said "they" "control what you hear, and what you don't hear, what is covered, how it's covered, even if it's covered at all".

The above quotes are from a speech Donald gave in St. Augustine, Florida, on October 24, 2016. I first heard them on MSNBC.

You may need to be fluent in Idiocratic Trumpery (or Inauthentic Authenticity) to understand the quotes, though. It's essentially a nonliteral language of nonsense. Many right-wingers think it's Grrrreat!
