"I know why she lost"
She lost because 11 million people sat out this election. That's it, that's all there is.
The fact is that most of this country leans blue, and when voters turn out, blue typically wins. This is why the GOP is doing everything they can to make sure people don't vote.
Trump has a vote ceiling of around 74, maybe 75 million. In 2020, 81 million people voted for Biden.
I get what you're saying, but apathy at that scale isn't calling democrats a horse. It's taking a backseat on your future.
