Conventional wisdom says she's too extreme to win a general election, but there are a lot of far-left who sit out the general election. Republican moderates are happy to vote for a far-right candidate. Democratic centrists may well vote for a far-left one.
Republicans will present any candidate as a socialist extremist anyway. They can't vote against her any harder than the voted against Biden. (They only lost 2020 because of a literal ongoing pandemic being wildly mis-managed. Democrats will likely not get that opportunity again.)
I am one of those "centrist" Democrats who doesn't particularly want the far-left wing to control the party. But I'd vote for that in a heartbeat over continued dominance by the alliance of theocrats and billionaire-worshippers.
Nate's gotta publish stuff to get clicks these days and feed the algo, I stopped paying any attention.
