If Scalia died a year earlier

[President Johnson]

Would the Republicans still have blocked any Supreme Court nominee by Barack Obama if Antonin Scalia died in February 2015 instead of 2016? Just a month after they took control of the senate.

[Okay, maybe Mike Johnson is a competent parliamentarian.]

The Republicans would have blocked any Supreme Court nominee by Barack Obama if any Justice had died or retired at any point at which they had a Senate majority.

Obama would have attempted a recess appointment. It was an election year in 2016; as a result, outcome would have nulified recess appointment. Having a recess appointment im Garland, would have improved Clinton chancea, on gun background checks

Garland would be narrowly confirmed, 51-49. Collins, Murkowsksi, Kirk, Portman, and Ayotte flip. Heller, Corker, Alexander, Flake, McCain, Graham, Toomey, and Rubio are maybes.

[MASHED POTATOES. VOTE!]

Obama would probably nominate Garland or someone like him. He was, after all, intended to be a "compromise" nominee, easier for the GOP, or their crucial swing Senators, to swallow. There was no chance for confirming any more liberal nominee.

That's why I opposed the notion of Clinton renominating Garland if elected.

It's impossible to know. At the very least, the GOP wouldn't be able to point to coincidental historical precedent, since they would not be able to not count Kennedy as a late appointment by saying "well the vacancy came open in '87, doesn't matter that he was technically confirmed in '88" (yes they literally used that line many times). I could possibly see a hearing being held, but I doubt there would be a floor vote. Also, this is impossible as the 60 vote rule was still a thing in 2015:

Garland would be narrowly confirmed, 51-49. Collins, Murkowsksi, Kirk, Portman, and Ayotte flip. Heller, Corker, Alexander, Flake, McCain, Graham, Toomey, and Rubio are maybes.
