Exit polling reported by The Advocate:
The exit polling found that among the 4% of California voters who identified as GLB, 63% voted for Clinton, 29% for Obama, and 1% for Edwards. In New York, 7% of voters self-identified as GLB and 59% voted for Clinton, 36% for Obama, and 3% for Edwards.
No other states were asked about this. A few other facts, after the jump.
The New York GLB results weren't really stunning - they broke 59-36 in Clinton's favor, but the general population ended up 57-40 for her. So, meh, it's not too far off the electoral results.
The California GLB results were 63-29 in her favor, while the general results were 52-42. That puts her double digits ahead among Californian queers than in the general population of that state. Speculate away in comments as to why.
And, since this polling is probably going to be repeated ad nauseum, let's keep in mind that it's based on self-identification to a person with a clipboard, so a lot of GLB's probably wouldn't out themselves in public like that, pinning down what "gay", "lesbian", and "bisexual" mean is pretty hard work anyway, and the questions didn't ask about the T-folk. I don't know if any of that would sway the results or how, and I'm not going to speculate, but it should be kept in mind before making sweeping claims about this data.
But it's still interesting to look at, and I hope that they expand this sort of polling to other states come November. Not all queers live in West Hollywood, Chelsea, and the Castro.
