Um, maybe because there are 200 million white non-hispanics in the USA and perhaps 41 million blacks? Do the math - 1/3 of 200 million is still a lot more than 90 percent of 41 million.
This is absolutely an election dynamic to watch in November. There is nothing wrong with a story talking about its possibility of changing the election's outcome but I do believe they missed one scenario to consider and that is whites might be less inclined to vote against a light-skinned black presidential candidate over a dark skinned black candidate.
It reminds me of a classic SNL skit with Garrett Morris and politician Julian Bond who hosted the show back in the 70s. They were on a segment called black perspective and they were talking about a perceived bias against blacks in IQ testing. You can view the entire segment
here but here is my favorite part of the skit.
Garrett Morris: Well, I think I understand the problem with the tests. But the fact is that people have been saying that white people are smarter than black for hundreds of years. We've only had I.Q. tests for 20 or 30 years. How did the idea of white intellectual superiority originate?
Julian Bond: That's an interesting point. My theory is that it's based on the fact that light-skinned blacks are smarter than dark-skinned blacks.
Garrett Morris: [ not sure he heard that right ] Say what?
Julian Bond: I said I think it might have grown out of the observation that light-skinned blacks are smarter than dark-skinned blacks.
Garrett Morris: I don't get it.
Julian Bond: It's got nothing to do with having white blood. It's just that descendants of the lighter-skinned African tribes are more intelligent than the descendants of the darker-skinned tribes. Everybody knows that.
Garrett Morris: This is the first time I've heard of it.
Julian Bond: Seriously? It was proven a long time ago.
