It really is not her place to say who the President chooses for seat on the USSC. But I guess she is like the rest of the people around the Clinton administration and have no respect for tradition.
Forget about tradition, she has no respect for the Constitution which does not require the POTUS to seek the advice or consent of anyone other than the Senate in selecting justices to the court. Nor does the Constitution require or even suggest that the POTUS must or should nominate a person who will advance the rights of women or any other group. The constitutional role of SCOTUS is to decide cases and controversies arising under the Constitution or the laws of the United States, no more, no less, without regard to personal beliefs and agendas.
