Kamala will probably be forced out before the Primary some how, she's pissed off the megadonors and they won't pony up for her again. AOC has no chance on the national stage, but I do agree she'll be in the running for the youth but as the new Bernie to syphon money out of them for the DNC. Newsom has been working to make himself seem like the frontrunner but I don't think he actually stands a chance at the nomination.
The Progs that ran(into the ground) Kamala's campaign believe they are the future leadership of the Democratic Party and are completely refusing to believe they need to move away from the far left. They want to go harder left, and we are already seeing that in Minneapolis and New York Mayoral primaries. Maybe if the progs really get their backs broken over midterms they will get them back on the reservation, but they'll probably disenfranchise them in the process. I don't see them giving up their entitlement if they cost the Dems the midterms though. I currently think Crockett is the current most likely candidate for 2028 Democratic Primary. The Progs are are a black woman political death cult.
But we are so far away from being anywhere close to high probability on 2028. Hell, this last week could be a boon the the DNC if the fallout comes down hard on the Progressives and Trump radicalizes them out of the party for the Democrats. Not enough to save them in 2026 but could rip off the band-aid they desperately need to in order to shift hard to center for 2028.
