Robert Gates: Hillary Clinton admits her changing position on Iraq war was purely political

From the Washington Post:

Gates offers a catalogue of various meetings, based in part on notes that he and his aides made at the time, including an exchange between Obama and then-Secretary of State Hillary Rodham Clinton that he calls “remarkable.” 

He writes: “Hillary told the president that her opposition to the [2007] surge in Iraq had been political because she was facing him in the Iowa primary. . . . The president conceded vaguely that opposition to the Iraq surge had been political. To hear the two of them making these admissions, and in front of me, was as surprising as it was dismaying.” . . .
