Enshittification

In my opinion, Harris lost because of similar actions—citizens trying to teach a lesson or punish their party for not being what they want it to be (which is a reasonable wish, but I’m not sure about the action)

The democrats were doomed to failure from the beginning. They consistently ignored their voters and were almost enthusiastically pushing people to the other side. To this day, most of the democratic leadership doesn't seem to have learned any lessons.

But what's infuriating is that the republicans pushed Trump. The traitor who attempted a violent coup against the American government, and who very clearly had plans to become a dictator and destroy democracy in this country is who they backed for president. If they backed some sane right or center-right candidate, they would have wiped the floor in that election with much more votes, much less drama, and possibly even restored a sense of national unity.

But nope. The republicans joined the American traitor, and now the entire world is going to suffer for it. If WW3 happens, I hope the equivalent of the Nuremberg trials remembers who got us to this point: it wasn't the incompetent Democrats, it was the fascist Republicans.
