A CNN/Opinion Research Corporation survey released Thursday indicates that 71 percent of the American public disapprove of how Bush his handling his job as president.
"No president has ever had a higher disapproval rating in any CNN or Gallup poll; in fact, this is the first time that any president's disapproval rating has cracked the 70 percent mark," said CNN Polling Director Keating Holland.
"Bush's approval rating, which stands at 28 percent in our new poll, remains better than the all-time lows set by Harry Truman and Richard Nixon (22 percent and 24 percent, respectively) but even those two presidents never got a disapproval rating in the 70s," Holland added. "The previous all-time record in CNN or Gallup polling was set by Truman, 66 percent disapproval in January 1952."
CNN Senior Political Analyst Bill Schneider adds, "He is more unpopular than Richard Nixon was just before he resigned from the presidency in August 1974." President Nixon's disapproval rating in August 1974 stood at 67 percent.
The poll also indicates that support for the war in Iraq has never been lower. Thirty percent of those questioned favored the war while 68 percent opposed the conflict.
"Americans are growing more pessimistic about the war," Holland said. "In January, nearly half believed that things were going well for the U.S. in Iraq; now that figure has dropped to 39 percent."
The numbers on the Iraq war come on the five-year anniversary of President Bush's "mission accomplished" moment onboard the aircraft carrier USS Abraham Lincoln, when Bush proclaimed that "major combat operations in Iraq have ended."
The record low support for the war in a CNN poll could be one reason behind the president's unpopularity, but it probably is not the only one.
"Support for the war, the assessment of the economy and approval of Mr. Bush are all about the same - bad," Schneider said.
The CNN/Opinion Research Corporation poll was conducted by telephone from Monday through Wednesday, with 1,008 adult Americans questioned. The poll's sampling error is plus or minus 3 percentage points.
