I would like to see information such as this on a widely-used public forum, such as Wikipedia. They are biased against Trump, they don’t permit original research, and they require all facts to be from reliable sources, but I think it can be done (at least partially).
To take a simple example: the Wikipedia article “2020 United States presidential election”, in the “Results by state” section, has a “Total votes” column. It could also have a “Registered voters” column for the number of registered voters, and a percentage column showing the proportion of registered voters who actually voted. This might show anomalously high percentages in the swing states.
The next step might be to show the corresponding sets of figures for each county in the state. (I looked up the Wikipedia article on Georgia, and it shows the total votes cast for each county. But that is not true for Michigan.)
And then at a still more detailed level.
The ban on original research might prevent comparing the average for the swing states with the average for the remaining states, but a graph, with an appropriate choice of scale, should be acceptable and could drive the point home (especially if the previous election figures are shown for comparison and they are noticeably different).
The requirement for reliable sources could be difficult because of the bias of the mainstream media, but small local media should be acceptable, and might even be more likely to publish the more detailed data.

Specifically their censorship.
