The last time this happened was 1868. Draw your own conclusions.
Since 1806, Senate Rules have remained in place. The United States Senate run by Majority Leader Mitch McConnel of Kentucky has deployed the "Nuclear Option" now so many times the system is broken. 51 Voting Senators is all it takes whereas the norm was 60. In 2013 for the first time the Democratic Senators led by Harry Reid of Nevada deployed this tactic for lessor court appointees, but not for Supreme Court Appointees, The Republicans have. 3 Times as of October 26th 2020.
The people of the United States of America are very angry at the the United States Senate Republicans for confirming the Justice when they are unwilling to pass additional stimulus payments during the pandemic. There is much angst online at the current administration.
Come November 3rd, should the polls prove correct, I fully expect the legacy of Donald J Trump to be wiped clean by several "Nuclear Options" for Supreme Court Justice appointees to rebalance the Court. First test will be November 10th 2020
That is my, and many other's conclusion
