In a USA TODAY/Gallup Poll taken Friday through Sunday, 28% of Americans approve of the job Bush is doing; 69% disapprove. The approval rating matches the low point of his presidency, and the disapproval sets a new high for any president since Franklin Roosevelt. The previous record of 67% was reached by Harry Truman in January 1952, when the United States was enmeshed in the Korean War.

Bush's rating has worsened amid "collapsing optimism about the economy," says Charles Franklin, a political scientist at the University of Wisconsin-Madison who studies presidential approval. Record gas prices and a wave of home foreclosures have fueled voter angst.

Bush also holds the record for the other extreme: the highest approval rating of any president in Gallup's history. In September 2001, in the days after the 9/11 attacks, Bush's approval spiked to 90%. In another record, the percentage of Americans who say the invasion of Iraq was a mistake reached a new high, 63%, in the latest poll. Assessments of Bush's presidency are harsh. By 69%-27%, those polled say Bush's tenure in general has been a failure, not a success.
