Other than the fact that I believe it's going to turn out to be a waste of time, it's probably necessary in this instance. If it changes anything, of course, it will have been worth it (even if that means Trump wins). If it doesn't change anything, it proves that contesting the result was political posturing and a waste of time. And if it shuts people up who refuse to believe facts, maybe that will have made it worth it, too. Also, I suppose, if it helps with the legitimacy of the upcoming runoff elections, then that will be a good thing, as well.
