>There's lots of research on election results and voting patterns.

Yes, thats the hard part. Lots of reach if varying quality and accuracy, before and after election analysis. Opinion pieces. So much to sift through.

>It's really on you or whoever is making the claim.

I didn't make the claim. But I want to emphasize that this isn't just a question you throw a link at.

>If you don't know, then these claims are fabrications.

If that's your approach to any social science, you're not getting far. Nro unless you have the money for a census with proper statisticians. Data will always be messy and debatable.

>It seems pretty straightforward to me. Who voted for what and why?

I hope the above at least sheds some light otherwise. At least if your goal is truly truth seeking and not randomly bashing heads on the internet.
