A lot depends on which piece of data you choose to make your point. One can "cherry-pick" data, or select certain results that make your viewpoint look good. Here's a lot more detail from the Newsweek article: (The actual poll results would make it clearer, but I didn't find those.)

...Support for Bush’s handling of the war on terrorism abroad has also dropped sharply over the past few months, from a 70-percent approval rating in late September to 55 percent this week. Thirty-eight percent of those polled say they do not approve of the way the president is handling the terror war overseas.



Four out of five polled agree that Americans would be safer and more secure if Saddam were no longer in power in Iraq. However, most prefer to try non-military solutions first in order to achieve that goal.



[Like what? Nobody has yet come up with a credible non-military idea for getting rid of Saddam. Maybe put a curse on him?]

A slim majority of Americans say they approve of the administration’s efforts to deal with Iraqi leader Saddam Hussein, while 38 percent say they disapprove—about the same split as in past polls over the last few months. And 63 percent say they would support military action, while 31 percent would not.

[This is where I cherry-picked MY number]

Four out of five polled agree that Americans would be safer and more secure if Saddam were no longer in power in Iraq. However, most prefer to try non-military solutions first in order to achieve that goal. Sixty percent say it is more important to take more time to achieve U.S. goals in Iraq without using military force, 35 percent prefer to move quickly with military force and see it as the only way to deal effectively with Iraq (five percent don’t know).



Support for war in Iraq declines dramatically when specific scenarios are raised.



[It also goes up dramatically when specific scenarios are raised, but this is Newsweek after all.]

Eighty-one percent of Americans support U.S. military action against Iraq if the U.S. joins together with its major allies and has the full backing of the U.N. Security Council.

[See? Eighty-one percent! A less scrupulous person would have cherry picked THAT number.]

But support drops to just 39 percent if the United States was joined by one or two major allies in the attack, but did not have the support of the United Nations.

[This is where the "most oppose" quote is cherry-picked from.]

There's a lot of other interesting things in this poll, and it's worth reading all of it.
