Most Americans want our troops out of Iraq and they want a timetable for withdrawal, a new poll says.

Reports USA Today:

A majority of Americans say Congress should pass a resolution that outlines a plan for withdrawing U.S. troops from Iraq, according to a USA TODAY/Gallup Poll taken Friday through Sunday. Half of those surveyed would like all U.S. forces out within 12 months.

The poll finds support for the ideas behind Democratic proposals that were soundly defeated in the Senate last week. An uptick in optimism toward the war after the killing of terrorist leader Abu Musab al-Zarqawi earlier this month seems to have evaporated.

Richard Eichenberg, a political scientist at Tufts University who studies presidential polling, says views on Iraq are too set to be changed by momentary developments, even positive ones.

“The other piece of quote-unquote ‘good news’ is the unity government in Iraq, but it’s not as if we’re hearing that they have made great strides in eliminating the militia influence or violence anywhere in Iraq,” he says. “There’s still a steady drumbeat of bad news.”

Bush’s approval rating is at 37%. After hitting the low point of his presidency at 31% in May, it rose to 38% in mid-June. His standing, which slipped below 40% in February, hasn’t rebounded above that level since then.

The percentage of Americans who say the president has “a clear plan for handling the situation in Iraq” has dropped to 31%, a new low. That’s still higher than the 25% who say congressional Democrats have a clear plan for Iraq.

The telephone survey of 1,000 adults has an error margin of +/-3 percentage points.

In the poll, 57% say Congress should pass a resolution that outlines a plan for withdrawing U.S. troops; 39% say that decision should be left to the president and his advisers.
