Here is one of her nodding over 400 times during a Sanders endorsement https://youtu.be/0k94Ww12U50
IRT post 62, Did some investigation work. That fun video link was condensed down to 6 minutes or so. The original full length video is about 2 hour long. Anybody that can stand to listening to Hillary and Bernie drone on and observe Hillary’s mannerisms can start about the 36:30 mark. Bernie speaks for about a half hour or so. Hillary is doing the total head nob/bob for about a half hour while Bernie drones on. Bernie hands off the Mic about 1:08. Hillary is still nobbin and bobbin while she gives her speech for the next 20 minutes or so. The full video can be seen at https://www.youtube.com/watch?v=Jv8WWBULPLA
