Hakim and a last-minute lobbying push by the U.S. ambassador in Iraq, Zalmay Khalilzad, underscored U.S. concerns that the referendum could turn into a divisive sectarian showdown. "Of course there are disagreements. We're watching a political process unfold, a process that has encouraged debate and compromise," Bush said, adding that Iraqis recognize that there has to be "give and take." Speaking earlier on Sunday, Khalilzad said Sunni approval of Iraq's new constitution would be key to the country's future political stability. He told CNN's "Late Edition": "If the Sunnis do not buy into this draft ... then it would be a problem. It could assist the insurgency." --SP 2224 Local Time 1924 GMT
