Bush's Disapproval In Gallup Within MoE of All-Time Record
by Chris Bowers, Tue May 02, 2006 at 03:36:11 PM EST
Gallup shows Bush at 34 / 63, for an overall net of -29. A net disapproval of -29 puts him only 2 points behind the all-time worst of Bush Sr. and Carter, who both cratered at -31. However, I want to emphasize the importance of a 63% disapproval number, because it is the third highest rating for a President in the long history of the Gallup poll. Both Carter and Bush Sr. never went past 60%. Only Truman, at 65%, and Nixon, at 66%, ever surpassed a 63% disapproval rating according to Gallup.
However, a difference of only 3% in a telephone survey of around 1000 people is not statistically significant. While his net approval keeps him in the Carter -- Bush I range, right now no President, at any point in his presidency, has had a greater percentage of the nation disapproving of the job he is doing. Not even Nixon during the height of the Watergate scandal. In fact, on July 15th, 1974, Gallup also put Nixon at 63% disapproval.
