According to the Reuters tracking poll, since June 13 Hillary's poll numbers have tanked among registered voters who are not straight -- falling from 65% to nearly 40%. Slightly more of them actually said they would vote for someone else or wouldn't vote at all (42%), way up from the 20% that they started with before the Islamic terrorist attack on a gay nightclub in Orlando.
Trump has also seen increasing support from the gays, from 7% to 17%, although that is still within the range that he had been getting earlier in the race.
The major change is Hillary's cratering support from the cultural left's sacred minority group du jour -- far lower than the previous low points in the race.
Quite simply, they see how weak she is on dealing with Islamic terrorism, and they may also have become wise to how many tens of millions in bribes Crooked Hillary has taken from Saudi Arabia and other Muslim countries that punish homosexuality with death.
The gays have also become far more in favor of a temporary ban on all Muslims from entering the country, a more extreme position than Trump is proposing. In early June, they were over 80% against the ban, and now are only 55-60% against. More are outright in favor, and more are merely uncertain (at least being open to it, instead of closed off to it).
Since the gays only make up 1-2% of the electorate, their changing vote patterns won't directly affect the election. However, if they are making their feelings known to their "straight allies" in real life or on the internet, it could have a rippling effect throughout the left-leaning electorate.
Their allies will not hear a subtle change in opinion, but one that says they've completely changed their minds and simply won't be voting at all. That's bound to start some awkward conversations and reflections among Democrat voters.
As with other culture war topics, this election is putting a stark choice before voters -- do you want an identity politics President who will only "feel your pain," or a results guy who will protect you from those trying to harm you and threaten your way of life?
