By current tallies, Prop 8 to eliminate gay marriage is leaning toward passing, 52% to 48%. It's disappointing.
You can see the voting broken down by age, gender, race, education on this CNN page.
As expected, the younger the voters, the more likely they are to oppose the proposition (i.e. favor gay marriage). The more educated they are, the more likely they are to oppose it. The highest income brackets are more likely to oppose it than middle-income brackets.
However, I find it interesting that the lowest income brackets (<$30k) also oppose the proposition. Why would this be? It goes against the education correlation.
The only explanation I could concoct is that perhaps younger voters are more likely to earn less than $30,000, so the income is more correlated to age than to education.
