For the Democrats:

President Bush’s approval rating dropped to the lowest of his presidency in a poll taken after a week of revelations about abuse of Iraqi prisoners and questions about whether Defense Secretary Donald Rumsfeld should keep his job.

Forty-six percent of Americans approve of Bush’s job performance in the USA TODAY/CNN/Gallup Poll released Monday. That’s 3 percentage points lower than his 49% in late January, early March and last week. A majority said they disapproved of his handling of Iraq and the economy. (Related link: Poll results)

The Bush decline did not produce new support for Massachusetts Sen. John Kerry, the expected Democratic presidential nominee. In a hypothetical matchup among likely voters, Kerry fell 2 points since last week — from 49% to 47% — and remained in a dead heat with Bush, who was steady at 48%.
