The New York Times says that the ABA's vetting process has deemed a significant number of Obama nominees "not qualified," and that a large percentage of those found not qualified are women and minorities:
The White House has chosen not to nominate any person the bar association deemed unqualified, so their identities and negative ratings have not been made public. But the association’s judicial vetting committee has opposed 14 of the roughly 185 potential nominees the administration asked it to evaluate, according to a person familiar with the matter.
The number of Obama prospects deemed “not qualified” already exceeds the total number opposed by the group during the eight-year administrations of Presidents Bill Clinton and George W. Bush; the rejection rate is more than three and a half times as high as it was under either of the previous two presidencies, documents and interviews show.
The story says that the demographic composition of the 14 prospects opposed by the panel has proved to be "awkward." The Times' source says nine are women (five of whom are white, two black, and two Hispanic), and pf the five men, one is white, two are black, and two are Hispanic.
