Ginsburg was confirmed by something like 92-3 if I recall correctly.
Even though she had a major background as legal counsel for the ACLU, her nomination was not strongly challenged by anyone at the time.
At the time that all Republicans save 3 voted to confirm her, she was the most radical and least qualified nominee in history.
Being female provides a cloak of protection that would not fit for WM nominations, no matter the legal and ‘wise WM’ resume.
