Seriously, thank you for taking the time to read and respond. The 3rd link is a long word salad of an article they probably could've done better with, some highlights:

Another long, contentious new calendar process then might mean uncertainty with real electoral consequences — perhaps even making it difficult for Democrats running in a competitive presidential primary to know where to campaign, hire staff and advertise.

“These early states really do condition the campaign. The early states don’t guarantee a winner, but they tell us who is going to lose, at least in the first rounds,” Redlawsk said. “The winnowing is very likely to be different if the first state is South Carolina, or Nevada, or some combination, than if it were Iowa or New Hampshire.”

The party can try and mitigate that by starting its 2028 calendar discussions early, potentially even weeks after next year’s election. (we'll see if this come to fruition)

It's effective when you take into consideration what DNC spokesmen require, "they did not reach the standards for their nomination: a candidacy that is "generally advocated and recognized in the news media,".

I can link articles and interviews by Bernie if you wish but I'm going to assume you know of the legal battles and statements made by him during the campaigning and after. "fall-in-line" is definitely my words, but then you go on to describe exactly what fall in line means. The term does come across as negative but the reality is he made declarative statements beforehand and has now changed his position in favor of what the DNC wishes to do... there are other terms I could use I guess but the general description is the same.

I incorrectly assumed you were using the "this is a foreign bot" defense and were telling other people to not drink the kool-aid that I see used all the time so actual conversations can't develop. It's why I included the you and I part so I do apologize for that.

I can't come to the same conclusion you have with the data, I've pointed out just a few of the ways in which the DNC jerryrigs their primaries and candidates. We see the manipulation of media and the cost of running a candidacy which completely undermines any contender. We aren't seeing any "viable challengers" because of decades of hurdles and organizations (both local and national) that limit those who are highlighted, which in turn allows the DNC to say "well we don't think they have a chance so they're not allowed to run". It's like a boxing match where every opponent of Biden's has to wear weights and have their hands tied but "Biden would've won anyways because he's the better boxer".
