Six in 10 Americans surveyed say the United States should have stayed out of Iraq, and more than three in four say that things are going badly there — including nearly half who say things are going very badly, the poll found.

Beyond the war issue, the poll found widespread concern over the nation’s overall direction. More Americans — 72 percent — now say that “generally, things in the country are seriously off on the wrong track” than at any time since the Times/CBS News poll began asking the question in 1983. The figure had been in the high 60’s earlier this year.

But the poll results made clear that the war continues to be the issue Americans are most worried about. Sixty-one percent of respondents now say that the United States should never have taken military action against Iraq, up from 51 percent in a CBS News poll in April and 58 percent in the same poll in January. Seventy-six percent say that things are going badly in the effort to bring stability and order to Iraq, including 47 percent who say they’re going very badly.

The nationwide telephone poll was conducted Friday through Wednesday with 1,125 adults. The margin of sampling error is plus or minus 3 percentage points.

A large majority of the public — 76 percent, including a majority of Republicans — say that the additional American troops sent to Iraq this year by Mr. Bush have either had no impact or are making things worse there. Twenty percent think the troop increase is improving the situation in Iraq.

A majority of Americans continue to support a timetable for withdrawal. Sixty-three percent say the United States should set a date for withdrawing troops from Iraq sometime in 2008.

While the troops remain in Iraq, the overwhelming majority of Americans support continuing to finance the war, though most want to do so with conditions. Thirteen percent want Congress to block all spending on the war. The majority, 69 percent, including 62 percent of Republicans, say Congress should appropriate money for the war, but on the condition that the United States sets benchmarks for progress and that the Iraqi government meets those goals. Fifteen percent of all respondents want Congress to approve war spending without conditions.

Atrios had some good comments on this too.
