People will vote for whoever can persuade them that their interests will be protected. That's why Trump has his populist schtick even if it's a load of horseshit. There is no intention of ever doing anything he has promised poor people, because you don't make (enough) money doing things that actually help poor people.
He will make the claim though, and then follow through on his promise to hurt scapegoats. That alone is enough to keep just enough people on his hook.
Meanwhile, recycling middle of the road Democrats who are way too willing to compromise their party's (supposed) values bc they're afraid of stepping on wealthy people's toes, only gives fuel to the argument that both sides are the same. The right knows this, and they very successfully use this argument (which is partially true) to create disinformation fueled voter apathy and control the narrative.
Using this strategy, the right doesn't even have to worry about actually winning over voters from the middle or left bc they can always fall back on the base who is motivated by a scapegoat. They don't even need a "good" candidate, they just need someone who can be persuasive enough.
It's like the saying " I don't have to have to outrun the bear, I just have to outrun you."
Frankly, if the Democrats actually support the values they claim, they should understand that in 2025, wealthy people need to have their toes stepped on. We are not supposed to have one America where the wealthy profit from exploitation, and another America where everyone else to get exploited. Acknowledging that fact, is the very persuasive elephant in the room that would actually go very far in persuading people the both sides argument isn't true. Except neither side is willing to address it.
Republicans won't address it bc keeping that elephant invisible is the entire reason they care about running this country. They need power and control in order to protect their own interests.
I would like to believe that the reason Democrats won't address it, is bc they have mistakenly convinced themselves that throwing endless piles of money into a campaign (via their wealthy donors) will help them create the most marketable candidate who can pull voters from the center and right. In other words, they're too focused on outrunning the bear rather than their opponent.
