I think there is an easy solution to this.
First off, a recount will not determine irregularities in voting. Second, if that is not the case, then Stein is asking for a recount based on votes for and against... Stein. As I see it, unless a PAC is paying for this, which they aren’t, contributions to Stein need to meet FEC laws. This means, anything over 2k for Stein is an illegal contribution and cannot be accepted by Wisconsin as payment for the recount.
Another excellent point.
I’ve read that since all of MI and much of PA use paper ballots not possible to hack, Stein’s evidence of fraud is strictly limited to supposed differences between actual results and polling, prior to and exit. I cannot imagine a PA judge granting a recount on those terms. To do so would say that poll results should determine election outcome.
