Who writes the last majority opinions of this SCOTUS term?

[Chancellor Tanterterg]

The other interesting one is the Indian Reservation case.  While it's not how I'd bet, there's about a 1/3 chance Gorsuch votes with the liberal bloc there and ends up turning a good chunk of eastern OK (including the entire city of Tulsa) into land governed by Indian tribal laws  and remove it from federal jurisdiction.  Honestly, it'd be very 2020 if that happens, especially since that case is on no one's radar.  If it does happen, the land in OK would still be an Indian reservation IIRC and a good chunk of OK's white population is going to absolutely lose it.  Remember, you heard it here first

Also, I'm tryin to imagine Trump's reaction to a justice he appointed writing the majority opinion in that case with the aforementioned outcome and it's friggin hilarious.

Eh, that "good chunk of OK's white population" has no real reason "to absolutely lose it." Counsel for the tribe focused the issue on a limited scope, arguing only that OK shouldn't have authority to prosecute Native Americans (as opposed to all people) for crimes committed on this land (because it's reservation land). That's the only outcome they argued for, & such an outcome would "only" upend the criminal convictions of Native Americans (again, not all people) for crimes committed within those boundaries.

Imo, the Court would be best placed to simply issue a narrow ruling declaring the land a legal reservation & restoring federal/tribal authority over the prosecution of crimes committed there by tribal members without explicitly affirming any larger change in legal authority.

You don't think this is prime Fox News culture wars fodder?  Also, a narrow ruling would surely lead to lawsuits regarding expanded authority.
