Yeah, those two aren't for real... I mean that AOC grabs enough attention from the progressive side that by not committing, there was always a chance a progressive comes along to drag out nomination, or even tilt the scales like Sanders did. By her voicing support now (still in 2023), just kills any real threat from the left. In others words, AOC already endorsed Biden, good luck trying to find a second megaphone big enough to sway the progress votes.
