It's not just Reps vs. AOC, it's just as often Dems vs. AOC
AOC vs Biden spat "AOC group condemns 'old guard' Joe Biden as candidate of 'no we can't'"
Lieberman vs AOC vs Lieberman spat "'New party, who dis?': Alexandria Ocasio-Cortez mocks Joe Lieberman after he said she wasn't future"
The next POTUS candidate will split the Dems. A moderate will annoy the progressives. A progressive will annoy the moderates. The divide is palpable. The time of the reformation is at hand.
