The Heritage Foundation’s “Morning Bell” daily email here compares Judge Sotomayor’s record to the oath of office that she will take if confirmed.  Heritage concludes: 

Before she is confirmed to a lifetime appointment to the Supreme Court,
Senators must engage in questions like the ones above to assure that
she will be able to uphold her oath to impartially decide cases and
that she will do so according to what the law says?rather than how she
would seek to change the law. The American people, and the
Constitution, deserve at least this much.
