WASHINGTON - Support for the war in Afghanistan has fallen to an all-time low, with most Americans saying the US should pull out ahead of schedule, according to poll results released Friday.

The CNN/ORC International survey indicated only 25 percent of Americans favored the war in Afghanistan. And a majority of Republicans voiced opposition to it for the first time since the war began in 2001.

Only 37 percent of those polled said things were going well for US forces in Afghanistan, while only 34 percent said the United States was winning the war.

Altogether, 55 percent of those surveyed said the United States should withdraw all its troops before the 2014 deadline, while 22 percent supported the timetable and an additional 22 percent said the administration should keep some troops in Afghanistan beyond 2014.

The poll, conducted for CNN by ORC International, surveyed 1,014 American adults by telephone between March 24 and March 25 with a sampling error of plus or minus 3 percentage points.

The Obama administration is sticking to its timetable to withdraw from Afghanistan by end of 2014, despite a deteriorating situation in the country.
