From what she have read in MI, the election will be certified on Monday. Then after that candidate can petition the SOS for a recount/challenge by Wednesday. TEAM Trump may be waiting until the petition is filed before they will announce their intentions. Also the SOS probably has to make sure all county elections offices are ready for a recount should there be one.
The MI SOS will review the petition when she receives it and act accordingly, which won’td be till after the election results are certified Monday. Unlike WI which only requires one be a candidate and can pay for the recount, in MI the SOS has the authority to reject a recount request and also must take any objections from other candidates to the petition under advisement. Also MI law requires some proof of fraud or irregularities or harm done to the petitioner in the counting, IOW you have to have some evidence and valid legal reason for the recount besides making every vote count.
PA will be the key IMO. If they are rightly blocked by a PA judge from pursuing a recount or legal challenge to the certified election results. I would not be surprised to see first Hillary formally withdraw support for recounts in WI and MI. Then the MI recount likely gets denied and Stein will not appeal. WI will go on and likely finish the recount well ahead of the Dec 13 deadline and the Rats will not try delaying tactics. It all hinges on PA, which we will know by middle of the week at the latest.
I got an email from Trump's campaign asking for help with a recount if it gets to that point. They're on this.
