Poll: 60 percent of Americans oppose Iraq war YOUR E-MAIL ALERTS Iraq United States or or Create Your Own WASHINGTON (CNN) -- Sixty percent of Americans oppose the U.S. war in Iraq, the highest number since polling on the subject began with the commencement of the war in March 2003, according to poll results and trends released Wednesday. And a majority of poll respondents said they would support the withdrawal of at least some U.S. troops by the end of the year, according to results from the Opinion Research Corporation poll conducted last week on behalf of CNN. The corporation polled 1,047 adult Americans by telephone. According to trends, the number of poll respondents who said they did not support the Iraq war has steadily risen as the war stretched into a second and then a third year. In the most recent poll, 36 percent said they were in favor of the war -- half of the peak of 72 percent who said they were in favor of the war as it began. Sixty-one percent, however, said they believed at least some U.S. troops should be withdrawn from Iraq by the end of the year. Of those, 26 percent said they would favor the withdrawal of all troops, while 35 percent said not all troops should be withdrawn. Another 34 percent said they believed the current level of troops in Iraq should be maintained. Asked about a timetable for withdrawal of troops from Iraq, 57 percent of poll respondents said they supported the setting of such a timetable, while 40 percent did not and 4 percent had no opinion. Only half the sample, or about 524 people, was asked the timetable question. The Bush administration has maintained that setting a timetable or deadline for withdrawal would only help terrorists. Americans were nearly evenly split on whether the U.S. would win the war in Iraq. Forty-seven percent of poll respondents either said the United States would "definitely win" or "probably win." Another 48 percent either said the United States could not win, or could win -- but will not win. The poll was conducted August 2 and 3. Its margin of error is plus or minus 3 percentage points, and plus or minus 4.5 percentage points for questions asked of half-samples.
