ABC News’ David Chalian reports: One day after President Obama campaigned for his opponent, the New Jersey Republican gubernatorial candidate, former US Attorney Chris Christie, today endorsed Judge Sonia Sotomayor for the Supreme Court. "After watching and listening to Judge Sotomayor's performance at the confirmation hearings this week, I am confident that she is qualified for the position of Associate Justice of the U.S. Supreme Court. Elections have consequences,” Christie said in a statement.”While Judge Sotomayor would not have been my choice, President Obama has used his opportunity to fill a seat on the Supreme Court by choosing a nominee who has more than proven her capability, competence and ability. . . . This is a historic moment and her inspiring success story should not only make the Latino community proud, but all Americans." Christie’s move suggests that Gov. Jon Corzine, D-N.J., is not the only candidate who understands Obama's popularity, and the president’s shrewd political play in nominating Sotomayor. His GOP opponent has embraced some of the Obama appeal in a very blue state, while continuing to hammer away at Gov. Corzine.
