Well, no.
In court is the place to present evidence to be subjected to examination and "proved" or "disproved".
Very strong evidence has to be presented to legislatures for them to decide they need to defend the votes of the people of their state from fraud- as the Constitution provides.
That proof is being developed in the courts.
In a battle like this, every tool should be used, every forum should be tried, every piece of evidence should be presented.
