Remember, he voted "present" when he was in Congress; the first presidential term was all Bush's fault; then the American people just didn't understand his programs that were failing; now it's the Iraqis to blame for his short sightedness.
For Obama, who four years earlier had distinguished himself from Democratic rival Hillary Rodham Clinton through his opposition to the war in Iraq, the fact he had withdrawn all U.S. forces from the country was a problem solved and a political chip to be cashed in come November.
It was also a way to once again draw contrasts with Romney, who criticized Obama for failing to secure a so-called status of forces agreement with the Iraqi government. The agreement would have granted immunity from Iraqi prosecution to all U.S. troops in country after 2011. Reaching such a deal -- a political risk for Iraqi Prime Minister Nouri al-Maliki -- would have allowed a contingent of several thousand U.S. troops to remain, largely to help with training and specific counter-terrorism operations.
