I swear if SCOTUS rules the other way on the only issue I agree with them on I'll be mad.
The only way I can see that happening is if John Roberts decides that Sandra Day O'Connor's timeline has to be respected (which is kind of silly and arbitrary but still a very John Roberts-esque thing to do) and he can get one other conservative on his side too (very unlikely but Kavanaugh and ACB would be most likely, Kavanaugh because he's most likely to flip with him and ACB because she might be a bit more woke on racial issues than the other conservatives.)
However if a case came up after O'Connor's timeline expired than Roberts would be a definite vote to overturn.
