There's a common type of voter that people don't really hear about, but it's a naive voter that makes a really really simple choice.

Did my life improve in the past 4 years? I'll vote for the incumbent or their party.

No? Grrr, other party...

Some people are legitimately this simple, because they don't want to try and pretend to understand the deeper issues, and don't think about the problem any more than that. They hate politics and don't want to care about it or understand it. They just react to how their life felt in the past few years and ignore mostly everything else, because their direct life experience is the only thing they trust.

And I've brought this up before, and said yeah some people are just that dumb, and someone was like "well what do you expect me to do, vote for the guy who made my life worse?" Literally this type of voter got very vocally upset and announced this was the right way to vote. They exist, and they vote, and they see no problem voting for a fascist as long as their rent went up under a Democrat, and will likely vote for a Democrat because their bills went up under a fascist.
