I want to emphasize that they will try to cheat Bernie.
You shouldn't trust anyone who claims to know the outcome for certain, because there are far too many variables.

That being said, Sanders has taken a commanding lead in N.H. and appears to be on his way to victory in Iowa as well. He's within striking distance in Nevada, which means that Bernie could sweep the first three states, and that would destroy Biden's phony "electability" platform.
At that point Bernie's machine could simply steamroll the other candidates and make history.

The MSM will be out to stop him. Wall Street and the MIC will try to stop him. The wealthy elites, both foreign and domestic, will try to stop him. The GOP will try to stop him.
But for now I want to focus on the DNC.

Muddy The Waters

What better way to keep Biden's pathetic campaign alive then by casting doubt about who is winning the states?

For the first time, the Iowa Democratic Party will report three sets of results from the party’s presidential caucuses. And there is no guarantee that all three will show the same winner.

Each set of results represents a different stage of the caucus. The new rules for the Feb. 3 contest were mandated by the Democratic National Committee in a bid to make the process more transparent.
...
There will be three sets of results: tallies of the “first alignment” of caucus-goers, their “final alignment” and the total number of State Delegate Equivalents each candidate receives...Caucus-goers whose first-choice candidate fails to get at least 15% of the vote can switch their support to a different candidate. The threshold can be higher at some precincts.
... The Nevada Democratic caucuses on Feb. 22 will also report three sets of results.

This is actually a good thing, but you can bet it will still be used against Bernie. Intentional confusion about the winning margin, and maybe even the winner, will be pushed by the MSM.

Also, since super delegates still exist, the MSM could still report pledged delegates as if they were no different and could vote in the first round of the convention.

What Voters?

In 2016, 200,000 New York City voters were illegally wiped off the rolls and prevented from voting in the presidential primary. This voter suppression was done by Democrats against Bernie supporters.
The NY Democrats tried to do it again, but this time they were blocked in court.

Will the Dems try it elsewhere? Probably, although it might look different.

An additional wrinkle is that California law allows the parties to choose whether to allow No Party Preference voters to participate in their presidential primaries. In 2016 and again in 2020, Democrats have said “yes” while Republicans have said “no thanks.”

But there’s a catch for NPP voters wanting to vote in the March 3 Democratic presidential primary: They have to ask for a Democratic ballot. That’s easy enough at a presidential polling place. But with voting-by-mail becoming the regular practice for a large and increasing majority of voters, NPP voters have to request a Democratic mail ballot, too.
...There’s an additional problem for hundreds of thousands of California independents: They have registered — mostly inadvertently — as members of the American Independent Party as opposed to registering with No Party Preference... None of these people will be able to vote in the Democratic presidential primary unless they re-register as Democrats or as NPP filers.

When you are losing, you change the rules

It's the least surprising, most anticipated development so far.

Democratic National Committee chair Tom Perez has nominated dozens of lobbyists, corporate consultants, think tank board members, and former officials linked to the presidential campaigns of Barack Obama and Bill and Hillary Clinton to serve on the Democratic National Convention (DNC) nominating committee this July.

Many of Perez’s nominees are vocal opponents of Senator Bernie Sanders and spoke out against his campaign when he challenged Hillary Clinton for the nomination in 2016.

Just as it did in 2016, the DNC appears determined to sabotage a Sanders nomination, foisting a collection of neoliberal and imperialist hacks onto the convention committee to hold back a popular rebellion against the policies of endless war and corporate free trade they have personally presided over.

This is a dangerous development.
If the Democrats think that they can cheat Bernie (assuming he wins a plurality of the delegates), and the Left will just take it lying down, they are in for a shock.
If Bernie is the top vote-getter, and they cheat him, it will literally destroy the Democratic Party.

The list of nominees, Sunrise Movement political director Evan Weber said Sunday, looks like “a who’s-who of people explicitly opposed to the progressive agenda.”
...The list of Perez’s nominees, Andrew Cockburn, Washington editor of Harper’s Magazine, wrote Sunday on Twitter, represents “The true, grim, face of the Democratic establishment.”

I personally think that they are bluffing.
They've just set the table to see if the Left will blink.

On the other hand...

Congratulations to our distinguished Board Member @MeghanStabler who was appointed to the Democratic National Convention Platform Committee by Chair @TomPerez
