Going to chime in with my personal takes of the last few pages.
I don't believe that liberals are smarter than conservatives. I believe that everyone is ignorant of most things. No one fully understands how the economy works. Very few people understand the pandemic policy. I don't think most people have much of an understanding on what is happening in Ukraine or Palestine. Most people don't understand most of math or science.
People are aware of different parts of issues, they're driven by different belief systems, they're informed by different educational backgrounds, they're informed by different media.
There's way too much information to be fully informed about pretty much anything. A lot of that information doesn't particularly matter for the big picture, but knowledge is an absurd uphill battle. A lot of the fun for science/social science/math/etc, that there's always more stuff to learn. There's always more questions to be answered.
I don't think liberals tend to be smarter, but I think they tend to be more self critical. A little less likely to have a black and white view on the world, and more likely to be trusting when they know they don't understand something. (This is anecdotal based on my experiences, so doesn't particularly mean anything.)
I somewhat believe that you can build people up to making completely different conclusions by appealing to them in whatever very personal way fits them. If you're a loving dad who is afraid for you child's safety that you can convince them much easier that "someone" (an immigrant) is coming for your children. Made even easier, when you have friends who already have those beliefs. I think you can whittle away at people and get them to believe almost anything.
I think that's what makes Fox News so successful at what they're doing.
Was it the case in 2016 that so many conservatives/Republicans endorsed Clinton? I know that there were some.
The polling seems so bizarre, when there are so many stories of Republicans endorsing Harris, and most of the early voting seem to be in favor of Harris. Engagement seems to be so much higher for Harris.
None of it might mean anything in the end, but it seems rather strange how strong the indicators look for Harris, when polling suggests otherwise.
Wouldn't it be interesting if Democrats ended up winning the swing states more than expected, and had a closer than expected matchup elsewhere?
