Based on the election results, the “policies more popular with the electorate” were fascist ones. More Americans voted for fascism than didn’t.

Obviously not among Democrats. Votership among Democrats was massively down. It turns out you actually DO need to give something for people to vote for. "Orange Man Bad" doesn't work as a campaign strategy when there are almost no substantive differences in policy between one party and the other. Hate it, but don't deny the truth of the fact, that you actually have to get voters excited to show up and vote for your candidate.

Harris could have made her campaign about Medicare4All, and frankly, she would have won.

Harris could have identified the fact that Israel was engaging in a genocide and that she would not support that.

Harris could have done any number of things to break with a status quo that is functionally not working for people, and she chose not to. Her literal campaign argument was "more of the same". She made the choice to proceed with a strategy, that, obvious to everyone as early as fucking January of last year, was not going to work. Biden and his policies were DEEEEEEEPLY unpopular. There were analytics on him back in March showing him having less than a snowballs chance in hell at winning the election, and it only got worse from there. And it was his policies; his governance. And instead of breaking with those polices and style of governance, Harris doubled, practically tripled down on them. And it was obvious and called out as a mistake at the time.

Blaming voters for your team losing is like blaming the rules of a game. Democrats fumbled the ball, massively, and want to blame the ref, or the court, or anyone but themselves. We could never fail, we can only be failed, is what will be written on the Democratic parties tombstone.
