The Horse has the results of the newest Zogby poll:

George W. Bush’s job performance ratings have reached the lowest point since his pre-Inauguration days, continuing a steady decline since a post-9/11 peak, according to a new Zogby America poll of 1,013 likely voters conducted September 3-5.

Less than half (45%) of the respondents said they rated his job performance good or excellent, while a majority (54%) said it was fair or poor.

A majority (52%) said it’s time for someone new in the White House, while just two in five (40%) said the president deserves to be re-elected.

The poll also has Dean leading the Democratic contenders.

He is followed by Massachusetts Senator John Kerry (13%), Connecticut Senator Joseph Lieberman (12%), and Missouri Congressman Richard Gephardt (8%). No other candidate polled more than 3%.
