Washington (CNN) - Americans are split over whether President Barack Obama is taking too long to make a decision on whether to send more U.S. troops to the war in Afghanistan, according to a new national poll.
But the CNN/Opinion Research Corporation survey also indicates that by a narrow margin, Americans think that in making his decision, the president should listen to the recommendations of the generals in charge of U.S. troops in Afghanistan rather than taking other matters into account as well.
The poll's Wednesday morning release comes just hours before the president is scheduled to hold another meeting with his national security advisers to discuss policy in Afghanistan.
According to the survey, 49 percent of people questioned say the president is taking too long to decide whether to increase U.S. troop levels in Afghanistan; 50 percent do not.
"There is a gender gap on this question, with most men saying Obama is taking too long and most women willing to give him more time," says CNN Polling Director Keating Holland. "That's due in part to the partisan differences between men and women, but gender differences on the use of military force, and maybe even differences in how the genders make important decisions, can also be contributing to the split."
The poll indicates that 52 percent think Obama should listen to the generals, with 48 percent saying the president should take other matters into account as well. But a troop build-up remains unpopular, with a separate question indicating that a majority opposes sending more troops.
What's going on? Roughly one in five Americans oppose more troops, yet also believe that Obama should pay attention to the U.S. military leaders in that country, says Holland. "That suggests that a lot of people who don't support a troop build-up are unaware of General Stanley McChrystal's request for a bigger U.S. military presence there," he says. "And that, in turn, indicates that the military leaders in the field might provide Obama some political cover if he decides to increase troop strength there."
McChrystal, the top U.S. commander in Afghanistan, has reportedly submitted a request for as many as 40,000 additional troops.
While the public is divided right down the middle over whether Obama is taking too long to make the decision on troops, the poll suggests that there is widespread agreement that Afghanistan will never have a stable democratic government. Only one in 10 people questioned say that will occur within a year; only a third say that will ever happen. That may be one big reason why 56 percent of Americans oppose sending more troops, while 42 percent favor increasing troop strength.
According to the poll, four in 10 support the war in Afghanistan, with 58 percent opposing the conflict.
The CNN/Opinion Research Corporation poll was conducted October 30-November 1, with 1,018 adult Americans questioned by telephone. The survey's sampling error is plus or minus 3 percentage points for the overall sample.
