Here are two cases Alito's former left-leaning social progressive law cleraks have come out in support of Alito citing his integrity, ability and fair-mindedness. By the way, the fact that the man had left-leaning progressive law clerks ought to be testimony in itself.
The first witness was a former clerk for Judge Alito, Nora Demleitner, a law professor at Hofstra University, who called Judge Alito "one of the greatest legal minds" of his generation.
A self-described "left-leaning Democrat," Ms. Demleitner said the judge has many supporters who are liberal, and that she believed his confirmation would not "pose a threat" to women or immigrants.

[Susan Sullivan] was one of Judge Alito's law clerks in 1990-1991, the year the Casey decision was decided. I consider myself a social progressive. I am a card carrying member of the ACLU, a liberal pro-choice advocate who supports abortion rights. I favor gun control support gay marriage and oppose the death penalty. I don't have a problem if you want to take "God" out of the Pledge of Allegiance. In short, no one is likely to mistake me for a conservative any time soon. Yet, I support the nomination of Judge Alito because I know from having worked closely with him that he is not a political ideologue and is not intent on advancing a conservative political agenda.
As a liberal, what scares me is not the prospect of having Sam Alito on the Supreme Court; what scares me is the way my fellow Liberal Democrats are behaving in response to the nomination. I’m appalled and embarrassed by the fear mongering, the personal attacks and what I see as an irresponsible and misleading distortion of his real judicial record as well as his character. Now the threat of a filibuster lurks and Senator Kennedy’s tirade about documents being concealed, seems like little more than a pretext to justify a filibuster.
