Nero asserts that gays are shifting away from the CultMarx left:
Maybe he's detecting the seminal stages of an impending shift but I suspect self-projection may be clouding his judgment.
I'd happily be proven wrong. Here, however, is how deviant sexual support shakes out in Reuters-Ipsos general election polling in a Trump vs Clinton match up (n = 683):
That's quite similar to the bugger drubbing Romney took in 2012:
This is more of an academic question than one of crucial electoral importance. Gays and bisexuals make up no more than 5% of the total electorate and tend to have demographic characteristics that favor the left (single, urban, irreligious, etc) even before sexuality is taken into account.
Yes, looking at the data here we see that Obama's strong margin of victory among gays was what gave him the edge over Romney, as both fared equally well among heterosexuals. But just like in the case of whites vis-a-vis Hispanics, if Republicans managed to do a few points better among heterosexuals the apparent electoral importance of gays would disappear.
