You don’t understand the graph data at all.
I understand it completely. The question is do the presenters not understand it, or are they trying to distract from the real fraud by getting people to chase easily disprovable nonsense. I also understand what is missing. Where are the plots of Biden delta versus straight party D? Not shown, probably because they have the same shaped curve.
Look at about 27:30 in the video. He says 45% straight party R (x-axis). He says that means the precinct is 45% Republican. Not true! Then Trump got 25% of the non-straight party R, thus the 25% Trump vote is "20% less than you would think".
No, it means Trump got 25% of the D voters which is pretty good. Also the downward slope of the curve means the more straight party R there are, the fewer of the Dems are likely to vote Trump. IOW the more outnumbered the D's are, the more likely they are to vote against Trump.
