Really, the media should try and pay some attention to what they write. From US News: Barack Obama Could Lose Six Percentage Points on Election Day for Being Black
Uh, no. See, the thing is, we only do the election thing once. Barack Obama (or anyone else for that matter) is got "given" a "normal vote" which he can either win or lose.
Now, if you want to say the polling may be more inaccurate as a predictor as some people are inflating Obama's numbers because they are afraid of being thought a "racist" if they say they support someone else...well then you may have something. But Obama has no moral claim to a percentage of the vote based upon polling data.
Now, the notion that is somehow "racist" to support McCain has been a prominently consistent theme of both the Obama campaign and the media so they really have only themselves to blame if people are lying to pollsters.
