If the DNC can be reformed, this weekend will be the first real step in that movement.
However, articles like this do not give me hope.

Democratic Party officials are on the verge of greenlighting a Bernie Sanders-endorsed plan to weaken the influence of superdelegates in the presidential nominating process. But it won’t be pretty.

As Democratic National Committee members arrived here Thursday for their annual summer meeting, outspoken opponents of the proposal acknowledged they were outnumbered. Still, they pledged an aggressive, last-ditch lobbying effort ahead of a Saturday vote, defying a call for unity from party leaders.

“We’re up against a wall,” said Bob Mulholland, a superdelegate and DNC member from California who helped organize opposition to the proposal. “We’re going to fight it like hell.”

Superdelegate reform is the absolute bare minimum of what needs to happen.
Other reforms concerning budget transparency are also critical.

“If the DNC rejects this, it basically rejects the will of the convention,” said Mark Longabaugh, a senior adviser to Sanders’ 2016 presidential campaign. “The left wing of the party would be outraged.”

Yet opposition to the proposal appeared to pick up steam in recent weeks, when Congressional Black Caucus Chairman Cedric Richmond argued publicly that the plan would disenfranchise elected officials who serve as superdelegates.

“There should be enough room in the process to include the perspective of local party activists and officials, and Members of Congress,” Richmond said in a letter to Perez. “One group should not be harmed at the expense of the other.”

After meeting with about 15 opponents of the proposal at the convention hotel Thursday afternoon, William Owen, a DNC member from Tennessee who is helping to organize the resistance, said, “I think we’ve got a shot at trying to slow this thing down.”
He said he expected “a close vote and a contested vote.”

Fuck the voters, amirite!?

The good news is that all of this controversy and bitterness can be blamed on one entity alone - Russia.

Momentum is growing within the Democratic National Committee for a significant reform to the party’s presidential nominating process, but the proposed change has caused a leading California Democrat to question whether Russian meddling is behind the effort.

The basis for his claim? An activist from West Virginia promoting the changes, who he had seen at two national party gatherings, admitted to him that she was a Green Party member and had voted for its nominee, Jill Stein, in the 2016 election.

“I concluded someone is picking up her expenses but there she and others are, demanding we change our Rules,” Mulholland wrote. “The Putin operation is still active.”

Damn Putin! Trying to make the Democratic Party more democratic!
