A new poll finds most Iraqis disapprove of the presence of American troops in their country, but are optimistic about this week's election and the country's future.

The ABC News poll, conducted with Time Magazine, says more than two-thirds of the Iraqis surveyed oppose having U.S.-led coalition troops in Iraq. It says half say the U.S.-led invasion was wrong, up from 39 percent in early 2004.

But it says 71 percent of Iraqis say their own lives are going well, with their economic situation improving.

The survey also says three-quarters of Iraqis expressed confidence in this week's parliamentary vote, and 70 percent approve of Iraq's constitution and want the country to remain unified.
