From someone who doesn’t really support either of them - Broadly speaking I don’t find AOC to be intentionally divisive as a political tactic. She’s under constant attack from the right and to a lesser extent moderate Dems and defends her viewpoints and sometimes yes she can be divisive. Kshama is incredibly divisive on purpose as a constant tactic - e.g. her recall campaign didn’t even argue the charges they just made it into an us vs them debate (also see thestranger coverage which essentially functions as an extension of her campaign). I pretty much look at Kshama as an ultra-left version of Trump. I doubt the recall campaign will be successful at the end of it but I guarantee if she loses by a small margin she will act just like Trump did after the 2020 election.
