I'm curious to know what questions were asked. I'm guessing it's more a matter of people not wanting to re-litigate the issue, rather than actually being more in favor of it. As usual, the media confuses the issue of whether people "support" it, or favor it; with the issue of whether they want government to do something about it.
Also, the media is spending more time on other matters, so no one's paying attention to the fact that the aftermath of the SCOTUS decision has resulted in restricting Americans' rights, rather than actually allowing or granting rights to anyone.
This...
always this.
For the sake of argument, the percentage of the population that is gay/lesbian is around 3%. That's roughly 9,642,000 out of 321,400,000 people in the U.S.
Now take out of that the percentage of them who actually
want to get married. And consider that a percentage of those in certain states before the SCOTUS decision already were married. Probably places that already had a higher per-capita gay population, meaning less of them in the states that didn't. And that most of those folks were probably living in a more-or-less "gay common-law marriage" scenario already.
The entire Gay Marriage debate, it really was a Phyrric battle of epic proportions. Both sides did themselves harm. The MSM/Left in it's zeal to normalize homosexuality, and in it's coastal/urban bubble gave a very very false impression, either an overt one or subconscious one, of just how large the gay population of the U.S. is. And that made it a "bigger problem" than it actually is/was, at least in terms of demographics or sheer numbers to those that were in opposition.
And in turn, their opposition made the gay marriage issue into a big club for the Left in the greater Culture War, and for the social/religious Right, they lost a major war, instead of conceding on what could have been a small skirmish. And arguably, they lost those freedom of/freedom from association rights in the process because it became such a contentious all or nothing battle.
The whole thing was just another example of how people are artificially drawn into the political Left/Right dichotomy, and are all tricked into ignoring the other equally important Authoritarian/Libertarian one.
How the MSM leads us ALL around by the nose, even those of us who nominally think they dislike/distrust the MSM via emphasis of
frequency in reporting and presentation is arguably a much much bigger issue than Gay Marriage ever was.
