It's more that Harris did such a terrible job that even the other side being literal Hitler didn't save her.

Remember that people who considered foreign policy (aka Gaza) to be the most important didn't vote. People who voted Harris did so because they either thought some other issue was more important or just didn't care. I think you'll get better insights from a "why didn't you vote" survey. That said it's definitely not the only reason Harris lost; it was her complete and utter failure at campaigning that allowed Trump to go around collecting swing states like they're fucking MTG cards.
I'm not American so I didn't really fuck up anything. I still it's the responsibility of candidates to get people to vote for them. I don't care if you didn't like it, but expecting people to vote for a pile of shit to avoid a bigger pile of shit doesn't work, has never worked and will never work. The DNC, enabled by "hold your nose and vote for her" folks, failed to consider this basic fact and that lost them the white house and senate. Well, congrats.
The fact of the matter is: People need more than sticks to do anything; they need carrots. Nobody, me included, cares if you don't like how people didn't fear your preferred stick enough; that's just how people work. The failure remains squarely on the DNC who, having the perfect stick in Trump, refused to prepare a carrot and opted for a piece of shit hoping to attract some flies from the neighboring mountain-sized pile of shit. Getting angry at voters is like getting angry at the wind for destroying your paper house; I mean okay but maybe don't build a paper house?
Biden wasn't really a centrist in the same way Harris was. Biden ran on a progressive-ish platform, and mostly backed it up with action. He sure as hell didn't run on fracking and locking up immigrants like Harris is.
It's just straight percent of voters I think. Then they're sorted left to right based on how important they were in 2020.
Adding to what the other two said, unions are supposed to be a way of the people to exert power, not just get better contracts. In less self-destructive countries unions organize for political causes all the time.
Just 5% of the population striking is enough to bring a country to its heels. That aside, if Americans were capable of this kind of collective action they wouldn't be in this situation to begin with.
Edit: Oh, and also: It seems Trump is winning the popular vote this time around.
Because the DNC would rather get Trump elected than listen to their constituency.
Okay that's just copium, but it's jot because she was a centrist either. Harris wasn't even trying to campaign competently or listen to her constituency; ultimately that's what did her in.
As easy as it is to blame voters, the American electorate didn't want fascism. That's just false. Harris dug her own grave by actively discouraging voters who didn't want fascism. This electorate is the same one that elected Biden in 2020 and (mostly) the same one that elected Obama in 2008 and 2012. They just wanted a real candidate and Harris wasn't that.
