“I made it absolutely clear that I would go forward with the confirmation progress, process as chairman, even a few months before a presidential election, if the nominee were chosen with the advice and not merely the consent of the Senate.  Just as the Constitution requires.  My consistent advice to presidents of both parties, including this president, has been that we should engage fully in the constitutional process of advice and consent.  And my consistent understanding of the Constitution has been the Senate must do so as well.  Period.  They have an obligation to do so.”
- Joe Biden, 2016

But the media doesn't want to mention this stuff.  The President has every right to nominate a Supreme Court justice, the Senate has every right to say 'yes' or 'no.'  That applied four years ago and applies today.  It's Democrats who decide things change for no reason other than them getting what they want.  Now they're campaigning on adding a lot more judges to the Supreme Court which even Ruth Bader Ginsburg opposed, not that they'll listen to her.

They're barely even pretending to want anything other than power.  At this point, the question is more about how long they've been planning this.  It was definitely underway during Obama, they were definitely working this way under GWB - I realized it was going on in November 2004 - and it's not hard to believe that this was being prepared under Bush Sr, Reagan, Carter, Nixon...  Look at how violent the 1968 Democratic Convention was.  They were working for Russia then...
