Washington ? Six in 10 Americans say they think the United States should withdraw some or all of its troops from Iraq – the highest number who have said that in the Gallup poll.

About three in 10 want the U.S. to withdraw all troops now, and about three in 10 said some troops should be withdrawn now. A majority, 56 percent, said they would be upset if more troops were sent to Iraq, according to the poll released Monday.

Support for staying in Iraq has also dropped in a Pew Research Center poll. People were about evenly split on whether the U.S. should keep troops in Iraq until the country is stabilized or bring them home as soon as possible.

Two-thirds in an ABC-Washington Post poll, also taken in early June, say they think the United States has gotten bogged down in the war in Iraq.

The Gallup poll of 1,003 adults was taken June 6-8, the ABC-Post poll of 1,002 adults June 2-5, and the Pew poll of 1,464 adults June 8-12.

Each poll had a margin of sampling error of plus or minus 3 percentage points.
