Who says people can't change (or flip-flop)? Sotomayor has proven that you certainly can...especially when you get nominated to the Supreme Court and you've got some otherwise inconvenient statements or actions in your past that you need to have people overlook.
For example:
On impartiality, Sotomayor had previously suggested that "there is no objective stance"...
In the hearings she stated: "The process of judging is a process of keeping an open mind. It's the process of not coming to a decision with a prejudgement ever of an outcome. (7/14/09)
But previously...
"There is no objective stance but only a series of perspectives...aspiration to impartiality...is just that, an aspiration..." (Women in the Judiciary, Women's Bar Association of the State of New York, 4/30/99)
On whether "predjudices" are appropriate, she said "predjudices are appropriate"...
In the hearings, she stated, "[I] Would Not Prejudge Any Question That Came Before Me If I Was A Justice On The Supreme Court." And, "I Don't Pre-Judge Issues."
But previously...
"I willingly accept that we who judge must not deny the differences resulting from experience and gender but attempt...continuously to judge when those opinions, sympathies and prejudices are appropriate." (Women in the Judiciary, 40th National Conference of Law Reviews. 3/17/94)
