If every fact she pled was accepted by the court, and every expert opinion she is relying upon found to be reliable, would you still think she hasn't pled enough to justify decertification of the election (setting aside the other remedies she asks for)?
I honestly don't know. I have no idea what the current discussion of remedies are and what precedent is. Maybe she does. Maybe she is right to jump right there. I'm not sure there is even a precedent for "well, we aren't sure about the mail in votes so all mail in votes should be discarded".
Like I said, the argument that it should be decertified and not counted is better. "We just can't tell because the whole thing is a mess and so in good conscience cannot declare any winner" is something that I think is extreme but if you have the evidence, it is warranted.
The argument that it should just be handed to Trump isn't really justified by a whole bunch of "we didn't get to see what happened but we suspect it is something bad".
Actual evidence of votes being switched from Trump to Biden - as in "we know these votes were switched and can do the math to give Trump the victory" then yes, "hand it to the other guy" seems fine. She doesn't actually even allege that though, from what I can tell. She says that maybe a bunch of votes were vulnerable and if you add up all of those it is more than the margin of victory.
It isn't usual to require a plaintiff to produce direct evidence of covert wrongdoing. Usually persuasive circumstantial evidence is sufficent to shift the burden to the responding party to provide a plausible innocent explanation for events which appear, prima facie, to be unlawful.
What do you base that on?
Leaving aside that we disagree about this being remotely persuasive circumstantial evidence, what makes you think that if I as plaintiff have sufficiently given evidence, the defense now has the burden to provide a plausible innocent explanation?
Anyway, we should perhaps be looking at the Michigan case, since she actually filed that one? The Georgia one still doesn't appear officially and the Cobb County GOP just said that she included them as a plaintiff even though they asked to be removed.
