I think that people are mostly politically ignorant and for whatever reason, do not take the time to educate themselves on the deeper working of our political system. Most people rely on mainstream news or their twitter feed or podcasts to stay informed about what is going on. This is why messaging is so important.
In the 2024 election, Trump talked about all the horrible things he wanted to do, but he framed it from the position of, "these terrible things will help you". Now to the politically aware folks like the kind that comment on political threads, we knew this was a lie. But we are the types of people to do research into crime statistics and know that immigrants contribute a minisicule amount of crime in the USA.
Regardless of how we wish people were more politcally knowledgeable, they aren't, so it is important for the oppositional party to do that kind of informing. The Dem party should have been out there calling the Repubs ridiculous and giga-racist. Kamala Harris should have had a strong message of protecting our immigrant neighbors against racist dog whistles and highlighting the good they do. Instead, the Democratic party ran on strengthening the border and cracking down on immigrant crime.
When the politically ignorant voter looked at these two candidates, they saw one who said, "immigrants are a problem and I'm gonna get rid of them all" while the other said, "immigrants are a problem and I'm gonna get rid of some". They heard Kamala Harris say she wants to spend more money building the border wall when only a few years ago, the Democratic party was calling the border wall racist and bad. The common voter saw the decision between Coke and Diet Coke, no matter how innaccurate that comparison was because the Democratic party advertised themselves as Diet Coke.
I really wish the common person would do a little more research into politics, but it isn't really surprising that they often sit out elections when the Democrats keep advertising themselves as Republican-lite. So while I agree that the constituency has some blame in the current atate of affairs, I think the Democratic leadership bears far more of the blame. They know what is popular and what would help them win, they just don't want to win with progressive policies that won't personally enrich them. This is why I think to fix our current state of affairs, most of our focus should be on the Dem leadership that are passively observing our descent to hell.
