Open to discussion, but since 2008, the Democrats have won every election where the leadership didn't "put their finger on the scale" in the primaries/picking the candidate. Obama, Obama; Clinton arguably shouldn't have been the nominee and Sanders should have; Biden was (?) properly primaries; Harris was picked
obvious pick, but still, not primaried.
Or the other reason, that the US is too sexist to elect a woman. It's depressing either way of course.
Same, an R4 with an i5 4670k I built in grad school. It's my ham radio computer now, as happy running Debian as the day I built it.
