Finally, you have the non-woke Bernie Bros. This 3rd camp probably hardly exists now given Trump has gifted them wins, but still a faction. Personally, I think Bernie and the more Progressives were the obvious answer to where the Dems head, but the party f'd them at every turn so they are no longer an option. Such a waste as they had Tulsi and RFK at one point yet threw them under, hell even 2016 Bernie wasn't that bad.
In terms of winning, only camp 3 really has a chance. It is likely an inevitability that some progressive will make it and do a Trump style take-over of the party now that they are extremely weakened. Really, the Dems just need a big man to turn up the same way Trump did, and they would be able to regain ground, only issue is that the party has been shown to kill off any opposition to the Clinton/Obama regime, so it will likely be awhile.
As for where Dems will head in 2028, bets are on them shuffling Mark Cuban out to be their "Trump" and have him sell healthcare. I doubt it will work as the party will clearly still have its tentacles wrapped around him, but I guess we wait and see.
