The Democrats have an absolute mandate to repair the damage done to the federal judiciary by a minority that has appointed it in a mistaken and corrupt sense of entitlement, the majority of the country disagrees with, and the Constitution does not recognize.
The democrats were busy playing by the rules. Putting the most qualified judges they could find into the federal courts. While republicans based their picks on ideology first, last and only.
That's why republican presidents set records for the number of unqualified (as judged by an ABA panel that reviews judicial qualifications) people they nominated to be on the courts. And the republican senate set records for the number of unqualified and barely qualified judges they packed into the federal courts.
Just look at the number of confirmation votes the current members of the supreme court received. It clearly shows republicans changed from qualifications, Such as Antonin Scalia, to ideology like Clarence Thomas.
