So I had been listening to Cruz and Crowder on the side, and there was something Cruz said which stuck with me.
Trump needs to win court cases in not one, but in at least three states, and he needs his legal team to work overtime to file the appropriate papers and present the appropriate arguments in order to do so. It is no trivial task to expedite matters either. There's a lot riding on them actually doing their job both correctly and quickly in order to beat the December 14th deadline. It would be in Trump's interest to only hire the best and the brightest for this, though I know not of who's actually on his legal team. (I believe a few state AG has already said public-ally they'd join the legal efforts?)
As some noted earlier and perhaps bear repeating, courts are typically reluctant to toss ballots away without a good reason, and there's a high bar to meet before they would consider doing so. I believe currently for both PA and WI, there have a rock-solid case to toss quite a number of the mail-in ballots, considering their violation of electoral rules are clear-cut and documented. It is less certain for states like GA, MI and AZ, because you'd need to both prove that the ballots were tampered with systematically, and that it has rendered the result essentially meaningless. Their case would be strongest in MI, certainly, since Detroit is basically scumbag central at this point. Less so in GA, and AZ. The best case for these states would be a full audit instead, where it is almost certain to find irregularities in the mail-in ballots, IMO.
