First off. Did you watch the documentary? Because saying its out of date tells me you didn't.
I'm not saying it couldn't work, but a big part of AOC's victory was catching an incumbent off guard in a safe blue seat. They're on their guard now. If AOC was running today, I think she would still win, but it would be much more difficult.
It worked because they brought together people who normally wouldn't vote. Less than 2/3s of americans vote. So this is entirely replicable.
If indeed >50% of americans are maga racists than the United States will dissolve.
edit: I'm Canadian and I will never set foot in the USA again. If y'all wanna roll over that's your prerogative.
