Pew Research Poll, or What a difference a year [and 30,000-100,000 dead Iraqi civilians, and 2,313 dead US troops, and blatant and willful violation of the Fourth Amendment and FISA law, and incompotent domestic emergency management] makes...:

"Bush's overall approval measure stands at 33%, the lowest rating of his presidency."

The president's ratings for handling of several specific issues, particularly terrorism, have also declined sharply. Just 42% now approve of Bush's job in handling terrorist threats, an 11-point drop since February. In January 2005, as Bush was starting his second term, 62% approved of his handling of terrorist threats.

In January 2005, Bush earned a lofty 89% approval from members of his own party, but that has declined to 73% in the current survey. Among independents, the number approving of Bush's job performance has fallen from 47% in January 2005 to 26% today; and Bush's support among Democrats, already quite low, has fallen by about half since the start of his second term (from 17% to 9%).

Bush's personal image also has weakened noticeably, which is reflected in people's one-word descriptions of the president. Honesty had been the single trait most closely associated with Bush, but in the current survey "incompetent" is the descriptor used most frequently."
