This is well worth watching if you haven’t seen the video-clip. AOC was far from “dumbfounded”, she didn’t seem to have any particular reaction to what the woman was saying beyond just wanting her to maybe calm down a little bit.
This was a masterpiece of political trolling, it revealed quite a lot about what the “Green New Deal” is really about.
AOC said “we still have time”—presumably eating babies might be an option after that.
