CNN) — More than 7 out of 10 Americans think government spending on the war in Iraq is partly responsible for the economic troubles in the United States, according to results of a recent poll.

In the CNN/Opinion Research Corporation poll conducted last weekend, 71 percent said they think U.S. spending in Iraq is a reason for the nation's poor economy. Twenty-eight percent said they didn't think so.

The weekend poll, timed to coincide with the Iraq war's fifth anniversary, also showed little U.S. support for the conflict. Fewer than one in three respondents — 32 percent — said they support the war, while 66 percent said they oppose it.
