Hopefully this ruling helps reverse all the private school voucher systems that are leeching money from funding that should be spent on public schools. For instance, Iowa has funding programs for both private k-12 (vouchers) and private colleges (Iowa Tuition Grant).
I don't know the lore behind SCO-OK, but I'd expect its composition to be the result of the same one-party state political process that gave us Jim Inhofe, Markwayne Mullin, Jim Lankford, and Mary Fallin. (I don't know much about the current Governor.) IOW, low expectations re: Establishment Clause.
