msnbc disputes this:
The main sample for the survey was a cross section of 700 registered voters nationally. As is the case with all of our usual polls, this sample is statistically representative of voters across the country, accurately reflecting the gender, age, educational, geographical, and racial makeup of the electorate. The column in the topline document labeled “All Voters”, as well as nearly all of the subgroups listed in the survey crosstabs, are among these cross section of 700. Eleven percent (11%) of these interviews — or 77 interviews — were with African Americans, which accurately reflects African Americans’ proportion of the electorate. Thus, African Americans are NOT over-represented in our national sample.

What I don’t understand then is why they only show 520 white voters in their sample. How do they get to the 700 if they are only adding in 77 of their black voters?
That, for starters, makes me think this poll was never meant to be accurate.
I'm not a statistician, but I remember hearing one say that political polls with fewer than 800 respondents were practically worthless.
Did they say how many were typical white people?
where is the polling data??? can’t find it anywhere...
