The thing is, the Plaintiffs' case does not mention "fraud," because it's too difficult to prove. This does not stop crooked Judges from dismissing cases due to "no fraud proven," despite nobody was even arguing that. A Federal Judge in PA did exactly that
"Fraud" will continue to be the lens through which many people incorrectly consider the case filed by Paxton, and unfortunately among those incorrect people there will likely be some USSC Justices.
I believe the evidence for fraud is very plain, even if it's somehow not adequate for Judicial action. But the salient issue is not fraud, it's equal treatment of votes among the several states, and within a given state. Even with no evidence for fraud the case is significant.
A blunt truth about this is that the red herring of fraud is largely brought on by Trump's own narcissism and the incompetent legal strategy that preceded Paxton's filing. Making the issue all about fraud focuses the issue on Trump himself and how he was personally cheated; his legions will join in lock-step chants and religious shibboleths to that end. It doesn't matter whether Trump was cheated, he's simply one person and people get cheated all the time. I suspect that over the course of Trump's life he has committed at least as much cheating as he's experienced from others.
What matters is whether north of 80 million American voters were cheated due to unconstitutional election processes, and whether we will continue to have a meaningful Constitution. Trump himself is a distraction. If SCOTUS rules in such a way that Biden is inaugurated *and* that the actions taken in the defendant states are permanently struck down and can never be repeated - non-legislative changes to voting laws, inconsistent regulation of ballots regarding voter personal data, observers barred from effectively observing leading to midnight visits from the Democrat vote fairy - this will be a significant win.
