WASHINGTON, Dec. 19 (Xinhua) -- Fewer than a third of Americans still support the war in Iraq, and more than half say they want U.S. troops out of the country within a year, according to a CNN poll released on Tuesday.

    Support for the nearly-four-year-long war fell to a new low of 31 percent, while a record 67 percent voiced opposition, according to the poll conducted Friday through Sunday.

    Nearly three-quarters said the Bush administration's Iraq policy needed a complete overhaul or major changes.

    Only 11 percent of those surveyed supported calls to send more American troops to Iraq, as President George W. Bush was said to be considering.

    Among over 1,000 American adults interviewed, only 32 percent supported keeping U.S. troops in Iraq "as long as necessary." By comparison, 21 percent said they wanted Americans to leave immediately, and 33 percent said they preferred a U.S. withdrawal within a year.

    The poll also found Americans were increasingly pessimistic about the outcome of the war, which had cost nearly 3,000 American lives since March 2003.

    Half of those polled -- an even 50 percent -- said the war was likely to end in a stalemate, while the same number said victory was no longer possible.
