Barack Obama's announcement today of Hillary Clinton as his secretary of state will be one of the year's biggest surprises. Politico runs an article looking at the development of Obama's and Clinton's relationship. It began cordially enough in the Senate, when Obama said he would look to Clinton as a model of how to handle political celebrity, but chilled in 2006 when Obama began preparing to run for president and Clinton thought he had not put in his time. The details of their primary battle are, by now, well hashed, but "I think that the people around each disliked the other candidate more than they ever disliked each other," says one Democrat. Obama repeatedly brought up Clinton as a VP possibility but was rebuked by his team. Throughout the fall, as Clinton campaigned for Obama in Pennsylvania and Florida, and with women voters, she earned his trust.
