It took some work to find this on the Washington Post’s website, but Obama has a narrower lead in their (and ABC’s) poll this week:

Negativity about the country’s financial prospects continues to lift Obama, but he now has a narrower advantage over McCain in Post-ABC polling than he did last week. Overall, the senator from Illinois holds a slim lead in the new national poll, with likely voters dividing 50 percent for Obama and 46 percent for McCain.

A few readers point out, FWIW:

You might want to note that in the print version the Post put Obama’s previous 9 point lead in a front page headline. Now that it has narrowed to 4 points I had to struggle to find any mention of it. They did bury a graph of the polls deep in the paper.
