However, if we look into history... they're the one that's been the guilty party. They're notorious for stonewalling GOP's SCJ nominations. It all started with the nomination of justice Bork, continue with Thomas, Alito and then Kavanaugh where he was accuse of sexual assault 30 years prior by a lib/dem activist who hated Trump without any evidence. Even her star witnesses refuted her story. The Dems destroyed the career of Miguel Astrada by stalling his nomination to the appeal court for 2 years, they called him "dangerous" because he'll be on track to become the first Hispanic SCJ.
Since 1980, Republican presidents have submitted 11 high court nominations to the Senate. They’ve lingered an average of 73 days, and earned an average of 71 votes in support. Democrats over that time have submitted four high court nominees. All of them have been confirmed, they were pending for an average of 67 days, and they were approved with an average of 79 votes in support. And no Democratic president’s picks have ever faced an attempted filibuster. Six Republican picks have.
But, the great and wise, Harry Reid changed the rule to benefit the Dems... all you need is 51 votes. Now, it's coming back to bite them in the @ss.
They are going as far as threatening to pack the high court if the GOP approve Amy Barrett... I say, go ahead and do it. Nothing is going to stop the GOP from doing the same, NO party is ever in majority all the time.
