On the surface it looks like Obama is breaking out. However if you look at the sample you will see the Washingon Compost oversamples Dems to get the results they wanted

and the Washington Post puts this poll, and gloats about the results on the front page

This Washington Post-ABC News poll was conducted by telephone September 19-22, 2008, among a random national sample of 1,082 adults, 916 registered voters and 780 likely voters. The survey includes additional interviews with randomly selected African Americans, for a total of 163 black respondents. The added interviews (commonly referred to as an "oversample") were completed to ensure there were enough African American respondents for separate analysis; the group was not over-represented in the reported results from the full sample. The results from the full survey have a margin of sampling error of plus or minus three percentage points. Error margins are higher for subgroups. Sampling, data collection and tabulation by TNS of Horsham, Pa.
