One of the factors that seems to have decided the election hasn't actually been swing voters.
Apparently LESS white men and women voted Trump this time. The only upswing in numbers was amongst Hispanic men and women.
The deciding factor seems more to be about turnout rather than swing voting.
Biden got substantially more votes than any other president. Preliminary estimates (as counting hasn't actually finished yet) show that Trump didn't beat Biden's popular vote total.
So Trump was better at getting the vote out and motivating voters to the polls than Harris was.
In other words Harris it's looking a lot like she lost because she didn't inspire democrat voters or she'd alienated democrat voters. So much of this smacks of disillusionment or wrong choice of candidate.
So while I don't think stuff like this changed people's minds about who to vote for, I do strongly suspect it may have had a bigger effect on the result than you give credit for because it enraged and motivated red voters to the polls whilst the vote of sane blue voters was depressed due to disillusionment because of a variety of reasons - stuff like the war in Israel, inflation, lying over Biden's health, a general lack of enthusiasm for Harris AND yes because of this issue.
A lot of the talk before the election was about white women in red states flipping democrat because of women's rights too. I think there's every chance that some wavered and considered it, but this issue may ultimately have persuaded them to stay put because the Dems would undermine women's rights in different, perhaps worse, ways in their mind.
We don't know. And we potentially won't ever properly know for sure because it's hard to pin this down in hard data.
What I am saying is that we can't dismiss the idea that this stuff didn't hugely affect the outcome of the election because it wasn't going to change anyone's already set minds on the subject, because the result isn't just about swing voters - we know that campaigns actually try and affect the vote by trying to motivate their own voters and depressing the opposition voters.
Looking at the data available this seems ultimately to be the key strategy the Trump campaign used. On voting day, Trump motivated voters on social media with claims of broken machines and election fraud which were widely shared and effective. I also have to say that dodgy poll in Iowa has a lot more questions to be asked about it than it might appear on the surface too.
