Does the Associated Press not understand margin of error?

Here's the rather breathless lede:

President Barack Obama's national standing has slipped to a new low after his victory on the historic health care overhaul, even in the face of growing signs of economic revival, according to the latest Associated Press-GfK poll.

The survey shows the political terrain growing rockier for Obama and congressional Democrats heading into midterm elections, boosting Republican hopes for a return to power this fall.

Just 49 percent of people now approve of the job Obama's doing overall.

It's a new low people! It's news!

Except that, of course, it's not.

According to the same Associated Press-Gfk poll, Obama had a 50 percent approval rating last September. Is the AP really now claiming it's a very big deal that over the last seven months the president's rating has dropped a grand total of one point in a poll that has a margin of error of four points?

Is that what really qualifies as news at the AP these days?
