Pulling this from another thread on the SC since there seems to be several posts regarding Mitch McConnell's support now vs. his non-support in 2016 of a nomination. There are lots of words being thrown around that suggest its a hypocritical move, its heinous, its a precedent being set, etc.
So, the idea that is a precedent isn't really one at all. I, myself, had said to someone mentioning this as a Mitch McConnell thing that it was more of a Strom Thurmond thing, then Joe Biden thing, then Mitch but it goes farther back than that. All the way back to the beginning, in fact.
So, in the history of our United States:
-There have been 29 times in which a vacancy came up during an election year.
Of those 29 times, the sitting president has nominated a replacement 29 times. That's batting 1000 for us sports fans playing at home. Every single time, the sitting president has made a nomination.
-Of those 29 times, the parties between the sitting president and the senate has been split (e.g., Dem president and republican controlled senate) 10 times.
Of those 10 times, 6 nominations were made before the election and 4 were made after but before the inauguration (the lame duck scenario).
Of those 10 nominations, 1 was confirmed (Cleveland administration).
-Of those 29 times, 19 nominations were made when the White House and the Senate were controlled by the same party.
Of those, 10 were nominated before the election with 9 confirmed. The other 9 were in the lame duck period.
So, it's not really unprecedented at all. It just happens to be much more magnified right now as we live in this hyper-partisan environment and the results are very much what you expect in that the parties in power, when unified, succeed and the when not, they typically don't. No one would be shocked by that.
