Gets overturned 6-3, along party lines. I don't eeven expect Roberts to side with the liberals here.
In addition to Roberts, I would be rather surprised if Kagan goes along with this. Most likely, I think they find some way to reverse 9/0 without reaching the merits. 8/1 with Sotomayor as the dissenter also wouldn't shock me if it reaches the merits.
I would be pretty surprised if any of the conservative judges go along with this, but if there's a wildcard it would be Gorsuch with a concurrence about states' rights and the word "conviction" not appearing in Section 3 of the 14th Amendment.
