To the best of my knowledge, the facts discussed in the lawsuit are not in dispute by Democrats. Instead, Republicans are alleging that the way the election itself was conducted in four swing states violated the Constitution.
The election changes were made due to the COVID pandemic, and the number of votes affected by the changes were obtained by the certified election results in each state, those vote totals are not in dispute, and those vote totals are large enough to put the results in each state in doubt.
So what the Supreme Court is being asked to do is declare those votes invalid. Whether they will take the case or rule in favor of Republicans is extremely unlikely according to virtually all legal and media experts…but the same was true for Bush v. Gore and we all know how that turned out.
(1) It's not 8mm votes (popular vote disparity) that needed to be flipped, it's only the disparity in swing states that needs to be flipped.
(2) If election voting systems were hacked, that could explain a large number of votes specifically in swing states. You can check the time series data from Edison Research which is publicly available on the NYT static data page to see the irregularities for yourself. For example you can see the Trump N votes decrement by X000s in MI and PA when it should be monotonically increasing. This might be an API glitch, it might be fraud, or it might have an innocuous explanation. Mainstream news doesn't report on these irregularities.
(3) Widespread fraud isn't alleged. Targeted fraud at swing states is the claim.
(4) Fraudulent ballots or vote switching by voting machines might have only flipped the POTUS choice. Dr Shiva had allegations on this which he's detailed in a YT video alongside data that he believes supports this hypothesis. Again, the mainstream media has not reported on this.
I've personally looked into (2) and (4) in some detail. I find (4) to be meritless and an artefact of the way they've presented the data. I find (2) to be totally real, but an innocuous explanation such as an API error to be much more likely than fraud.

Clearly, they didn't change downballot races, because that would be suspicious. Any group smart enough to cheat at this scale would be smart enough to not make it obvious.
CodeMonkeyZ on Twitter is biased, but links to interesting material nonetheless, such as excerpts from Dominion software manuals describing such oddities as vote tallies stored as floating point rather than integer values (seriously?).
I do believe some election fraud happened, how could it not with 150MM voters in this past election. But I have yet to read a single article that could outline any explanation for how democrats stole 8MM votes so Trump lost, but did not change down-ballot votes so that they also lost house seats and other smaller elections (that matter for re-districting etc).
