A record high (but not the Dow)

According to the latest Gallup poll (April 18-20), George W. Bush has received the highest disapproval ratings of any president in the 70-year history of the organization. Fully 69% of those who responded disapproved of his performance, while 28% approved. Fewer than 4% expressed "no opinion," and extraordinarily low number.

Prior to the latest survey, the highest disapproval rating — 67% — belonged to Harry S. Truman in 1952. Even Richard Nixon had a 66% rating at the time of his resignation in 1974.

The latest Gallup result offers more evidence to support the growing consensus that Dubya is the worst president in U.S. history.

The Gallup result is consistent with Pollster.com's current "trend estimate" for 19 national polls that show an average approval rating of 28.3%.

Meanwhile, Pollster.com's trend estimate for the Democratic race shows Obama with a 50-40% lead as of April 21st, the day before Clinton's 10-point win in Pennsylvania.
