Age & income: South Carolina exit polls

By Razib Khan | January 26, 2008 9:51 pm

Was checking out the exit poll data. Two things that jumped out at me….
Here are the votes for Obama from non-blacks in the South Carolina primary by age:
18-29 – 52%
30-44 – 25%
45-59 – 23%
60+ – 15%
Here are the votes by income for Edwards:
Under $15,000 – 14%
$15,000-$30,000 – 15%
$30,000-$50,000 – 16%
$50,000-$75,000 – 22%
$75,000-$100,000 – 26%
$100,000-$150,000 – 24%
$150,000-$200,000 – not enough data
$200,000 or more – 29%
Update: Andrew Sullivan says:

Then this: Obama won every demographic among the religiously observant. And the more devout they are – judging by their church attendance – the better he did. His narrowest margins against Clinton and Edwards were among those who never attend church services.

In New Hampshire and Nevada we have data which suggests Obama is stronger among the more secular (no data from Iowa that I can see). But I think the most plausible explanation is that what you’re seeing in South Carolina is the impact of the black vote; blacks are more religious than whites. Just as younger whites (there aren’t many Latino or Asian American voters in South Carolina from what I can tell from the exit polls) were more favorable toward Obama than older whites, I would be willing to bet that wealthier and more educated whites would also lean in his direction compared to poorer and less educated whites. Whatever you might say about it, but Obama does have a diverse coalition, and not just in terms of race. (though to be fair, one can say that about the Democratic party as a whole of late, with a coalition of racial and ethnic minorities, the remaining white working class vote as well as social issue driven professionals).

    “votes for non-blacks”? Define? Is that votes for anyone but Obama?

  • razib

    thanks. typed too fast! it’s votes for obama.

  • Coturnix

    Oh, you mean voted for Obama by non-blacks by age. Totally different.

  • Coturnix

    “Under $15,000 – 14%”, etc.
    Is that the percent of all of Edwards votes, or a percent of all voters in this income group voting for Edwards?

    Thanks – I should have done the math and added up the numbers – the answer would have been obvious 😉

    I have heard people voted for him just to vote against Clinton. News from other countries said it wa obviously a race vote in SC.
