Yes, that's the other side of the coin. The DNC fucked up so badly in many ways, and it wasn't their first time.
It's complicated. Some polls said Harris would win, along with Allan Lichtman who has been right about every election since 1984. However there are other signs that Trump was going to win. Also further complicated that Trump has a 30 year history of cheating and lying to win, and he and Musk would do everything in their power to not go to prison. Also also, Russia/China/Iran love to stoke and accelerate internal divisions by pushing election denial conspiracies. So overall, there's a lot of variables here and I would sleep better with PA having done a full hand recount (though I know that won't actual happen).
