HOPEFULLY SHE'S PAID HER TAXES (FINGERS CROSSED)
It just has to be 2nd Circuit Appellate Judge Sonia Sotomayor. Not only would she be the second woman on the court, but the first Hispanic in U.S. history. If you believe the Latino vote swung the last election towards President Obama (I don't), then this milestone would be a significant thank you.
Sotomayor, who is known as the judge who ended the ruinous 1994 Major League Baseball strike, is quite attractive other than demography. If Obama is hoping for uncontentious confirmation hearings, the 54-year-old Puerto Rican might placate Republicans. She is fairly moderate and was appointed by President George H.W. Bush to the U.S. District Court in New York.
Of course, these things look easy on paper. If chosen by Obama, Sotomayor's entire life will be examined. Every single piece of writing from college term papers to her decision on the second circuit will be examined for clues to her "real" judicial compass while hoping she does not share a peculiarly common trait amongst Obama nominees of not paying her taxes.
Salon lays down the skinny on other possible selections in an article posted shortly after election day that includes the other possible woman, Elena Kagan. The Daily Kos also has a quick thumbnail on Sotomayor.
