http://www.weeklystandard.com/blogs/gallup-biased-against-obama_647457.html Something I thought was interesting in the counter-argument: 5. All of this misses a much bigger point. Blumenthalâs criticism of Gallup is directed at its poll of adults, and specifically for having white adults comprise roughly 71 percent of its poll rather than roughly 68 percent. But what is not mentioned is that whites make up a larger share of the electorate than 68 or even 71 percent. Even in 2008, when Obama generated a 27 percent increase in the black vote, whites still accounted for 74 percent of all voters. This means that, when it comes to measuring the electoral relevance of Obamaâs job approval rating, the Gallup poll is still âskewedâ toward the Democrats. It just happens to be less âskewedâ than other polls.* * (emphasis mine)
