So I watched it the other day on the plane. I can't say it is complete hogwash so no free beer for me
I will first give my overall impression then some more detailed criticism focused on study quality and specific statements made.
Overall I think they show by clear evidence that there was some illegal ballot harvesting. The argument that it would have affected the outcome of the election is perhaps suggestive, but not much stronger. They make a number of clearly unwarranted and hyperbolic claims.
More specifically:
The argument that illegal ballot harvesting was widespread is quite weak. They demonstrate a few examples that really look like that is what was going on. But they do not state that how often they observed this as a fraction of the total or total number of times. They do not even attempt to estimate that fraction with random sampling of their dataset.
The argument that payments were made for this harvesting in general way is almost non-existent. There are a few examples where it sure looks like the people dropping the ballots are attempting to cover their tracks and one or two interviews, but no substantial proof of this in a broad way is adduced.
The argument that this would have affected the election is quite weak because of the lack of some obvious checks. They targeted what they said were far left non-profits. OK, but what would happen if you targeted similar right wing groups. Maybe this sort of thing was happening on both sides. They could have easily performed this type of analysis with their dataset but failed to do so.
Here is an example of a very hyperbolic claim made in the video - "Know for a fact that there was coordinated systematic fraud" (at ~46:34). My goodness, there is perhaps some evidence that some fraud went on, but hardly anything approaching reasonable evidence for this strong claim. Quite honestly, the fact that they would think this is an appropriate claim based on this evidence and that the people they were interviewing endorsed that seriously impugns the reasoning employed in terms of objective investigation.
Those are my comments from an objective analysis point of view. I will be gone for the next week and one half, so likely will not respond further until I return.
