From Wiki- It looks like Romney could have a full hour debate on Libya all by himself:
"Concerning the involvement of the American military in the 2011 Libyan civil war, Romney initially said in March that Obama had waited too long before becoming involved, and he also criticized Obama for ruling out the use of United States ground forces.[183] The next month, he said that he supported the "specific, limited mission" of enforcing a no-fly zone, but that Obama's support for the ouster of Libyan leader Muammar Gaddafi constituted "mission creep and mission muddle."[183] In October, after Gaddafi's death, Romney said, "I think people across the world recognize that the world is a better place without Muammar Gaddafi."[183]
Maybe Obama's position in each debate should be to show Romney has taken both sides on each issue,"Mr. Romney on X date you said _______. That contradicts what you just said Which is your real position?"
