The Democratic party has a huge problem. It's also a pretty simple problem: If the US equivalent of the Australian Electoral commission got caught picking a favourite between one of the two major parties there would be a royal commission and a complete overhaul of our political system.
It's really not comparable. The Democratic Party is, fundamentally, a private organization. While I agree that, in principle, the DNC shouldn't favor one candidate over another in the process of choosing who the Democratic candidate for a particular office will be, it's entirely different from the actual election to a public office. As an analogy, the DNC is like a team's manager, not the referee.
Waste not, get your budget cut next year.
