Constitutional election consequences prevented you from flipping Scalia’s spot with Garland, nothing more, and nothing less.
And your party’s decision under Harry Reid to open judge placement to simple majorities votes in the senate in 2013 combined with the President Trump’s unexpected victory opened the door for Gorsuch, Kavanaugh, and Amy Coney Barrett.
Interestingly, you always fail to recall that Chuck Schumer said that he was planning to use the same 50 vote majority on SCOTUS nominee as Reid had used on federal judge appointments during the lead up to what he expected to be Hillary’s coronation in Nov 2016
You fixed the game and then subsequently lost at it.
Elections have consequences - even suspicious nonID elections.
You will change the rules again if you can, and there is nothing to block it constitutionally. It will be incredibly foolish, but you will do it in the same heartbeat that you would have applied Reid’s Rule.
But there is that little Manchin problem, isn’t there? Pesky voters!
Let us all hope that Elections still have consequences.
