The petitioner pays the cost of the recount. In Wisconsin this was estimated at $1.1M initially. I have not seen the estimates for OH or MI, but should be higher. The last I saw, Stein had raised $5.5M and counting, for this effort, via online appeals that contain fine print indicating that any funds beyond that actually used in the recount(s) would be used for election accuracy/transparency advocacy in general. In other words a slush fund to give Jill Stein a platform into the future.
So, my suggestion for Wisconsin AG Brad Schimel is - stick a few crowbars in the procedural gearbox (the left does this all the time and are experts at it - take a few pages from their play book) and make the costs of the mechanics of the recount astronomically high (hire the most expensive accounting and legal consultants, etc.) to burn as much of Jill Stein’s slush fund as possible. Just means less of her noise to put up with next year, and the year after.
In WI, $1.1 million is the filing fee. Counties are in the process of estimating how much it will cost to do the recount-it will easily surpass $1 million. That additional cost is borne by the petitioner, AKA Stein. On top of that are the lawyer’s fees, also borne by the petitioner (unless they are Democrat hacks doing pro bono work).
She probably has enough money for a WI recount, but not enough to do MI and PA, as well. The fund raising will continue.
