Will a Sour Economy Trump Obama's Foreign Policy Victories?

President Barack Obama's on a foreign policy roll: the death of Moammar Gadhafi, the assassinations of Anwar Awlaki in Yemen and Osama bin Laden in Pakistan. Obama's withdrawal from Iraq and the successful NATO air campaign in Libya reaffirmed his credentials as a wartime leader. But conventional wisdom holds that none of this will matter because his political fortunes will be determined by the US economy. How will voters weigh his foreign policy victories against a sour economy? Will Republican candidates still try to make the case that he's weak on national security?
