At this rate, the GOP needs to get Kennedy to revoke his retirement if they want a conservative-leaning Justice on the Court through 2021
At this point I wish he could do that, but his retirement has already gone into effect some time ago. He is no longer a justice and would need to be re-confirmed 
That is true, however unfortunately. Alas, maybe such an option, him rescinding his resignation & showing up to work again on October 1st, wouldn't only be feasible but perhaps actively discussed if he had tendered his resignation pending confirmation of a successor. But he retired on July 31st, full stop. I doubt anybody in June thought it'd matter much. *sigh*
