WASHINGTON, April 9 (Xinhuanet) -- Two polls released Friday showed that the high-profile testimony by US National Security Adviser Condoleezza Rice before the 9/11 commission yielded mixed results for the White House.

    Compared with two weeks ago, fewer Americans now think the Bushadministration failed to do all it could to prevent the Sept. 11, 2001, attacks, but nearly two-thirds think the White House had no strategy to take out al Qaeda prior to the attacks, according to aCNN/TIME telephone poll conducted Thursday night.

    Forty percent of the 1,000 Americans polled said the administration, based on the information it had, could have done more to stop the terrorist attacks, compared with 54 percent in a CNN/USA Today/Gallup poll conducted March 26-28.

    But sixty percent of those questioned said the administration did not have a strategy dealing with al-Qaeda network before Sept.11, 2001.

    Meanwhile, a CBS News poll showed that Rice's testimony may have improved her own image with the public, but most Americans still believe that the Bush administration could have done more toprevent the Sept. 11 attacks.

    In March, a Gallup Poll found that 50 percent of Americans had a favorable view of Rice, while 25 percent were unfavorable. The CBS News poll showed 56 percent favorable and 17 percent unfavorable about her after the testimony. Viewers of the hearingswere even more positive.

    One opinion left unchanged by Rice's testimony is the continuing belief that the Administration is not telling the entire truth about what it knew before Sept. 11. Three out of fourAmericans, about the same as a week ago, say the Administration ishiding something, with one in ten going so far as to say it is lying.

    Despite the positive evaluations of Rice, there is only limite devidence in the poll that her testimony changed minds. Americans are more likely now to say that the Bush administration did all itcould to prevent the 9/11 attacks than they were one week ago, but60 percent of Americans still say they could have done more, according to the poll.
