WASHINGTON, Feb. 28 (Xinhuanet) -- The approval rating for U.S. President George W. Bush's job performance has fallen to 34 percent, an all-time low, from 42 percent last month, a new poll released on Tuesday showed.

    The CBS News poll found that 59 percent of respondents said they disapproved of Bush's job performance, in the aftermath of a security debate over a port deal under which a company from the Middle East would take over some operations of six major U.S. ports from a British company.

    Seventy percent of Americans thought the transaction should not be allowed to go through, and only 21 percent sided with the White House that the deal should be allowed.

    On Iraq, Bush's approval rating fell to as low as 30 percent, amid recent violence in the war-ravaged country, a seven-percentage-point drop from January.

    Sixty-two percent of those surveyed said U.S. efforts to bring stability and order to Iraq were going badly, while 36 percent said things were going well.

    On the war on terrorism, the president's approval rating also dropped to an all-time low of 43 percent, from last month's 52 percent. Fifty percent disapproved of his actions on the anti-terror war, up from 43 percent last month.

    The poll of 1,018 adults was conducted last Wednesday through Sunday, with margin of error of plus or minus three percentage points. Enditem
