"The problem for President Bush is a growing perception that he simply isn't competent. That's the story behind the polling numbers that have declined - bad week by bad week - since February 2005 when the president's approval rating stood at a respectable 52 percent. The predecessor whom Bush has begun to resemble isn't, as many liberal Democrats seem to believe, Richard Nixon. It's Jimmy Carter. Carter's political demise began when the American people, including many Democrats, started to perceive him as in over his head in the Oval Office. That's what may be happening now to Bush."
