From the "Today" show this morning:

RUSSERT: And Matt, the most astounding number in this: 2 percent – just 2 percent - of African-Americans give George Bush a positive rating for his performance as President. The memories of Katrina very much in their minds.

LAUER: Is that what this is all about? I mean, obviously that is just a startling number, 2 percent of African-Americans. Is this all about the aftermath of Katrina?

RUSSERT: Well, the imagery of that along with the economy and fuel prices and Iraq, but that event, Matt, really did have a searing effect. George Bush and the Republican Party has tried very hard to reach out to African-American voters, but this is a very dramatic setback. I cannot find a pollster who can remember any President ever getting just 2 percent approval from African-Americans.

Update:

To be fair, the margin of error on the poll is 3.4% percent. So Bush’s actual approval among African Americans could be anywhere from -1.4% to 5.4%.
