>am convinced the DNC is using canned applause and hoots
Yep. Couldn't have been more obvious during the 2015 DNC convention. The Fake Media were more than complicit. There were times when you could hear the crowd cheering and clapping, and as the camera panned the crowd the people were just standing there, neither cheering nor clapping.
(The video was not matching the audio),
Director: "Cut to camera 1."
And let's not forget that during the second debate, the media was also complicit in hiding the teleprompter hidden in Hillaroid's podium.
