Some insight into the Sotomayor pick.

She is just what Barry was looking for.

The problem I face — a problem that has been voiced by some of my other colleagues, both those who are voting for Mr. Roberts and those who are voting against Mr. Roberts — is that while adherence to legal precedent and rules of statutory or constitutional construction will dispose of 95 percent of the cases that come before a court, so that both a Scalia and a Ginsburg will arrive at the same place most of the time on those 95 percent of the cases — what matters on the Supreme Court is those 5 percent of cases that are truly difficult. In those cases, adherence to precedent and rules of construction and interpretation will only get you through the 25th mile of the marathon. That last mile can only be determined on the basis of one’s deepest values, one’s core concerns, one’s broader perspectives on how the world works, and the depth and breadth of one’s empathy.

In those 5 percent of hard cases, the constitutional text will not be directly on point. The language of the statute will not be perfectly clear. Legal process alone will not lead you to a rule of decision. In those circumstances, your decisions about whether affirmative action is an appropriate response to the history of discrimination in this country or whether a general right of privacy encompasses a more specific right of women to control their reproductive decisions or whether the commerce clause empowers Congress to speak on those issues of broad national concern that may be only tangentially related to what is easily defined as interstate commerce, whether a person who is disabled has the right to be accommodated so they can work alongside those who are nondisabled — in those difficult cases, the critical ingredient is supplied by what is in the judge’s heart.
