After 2016, the DNC already halved their influence. I’d argue they are a necessary evil to prevent various scenarios where bad actors try to hijack a primary.
But more generally, the entire point of a political party is to express political preferences via a platform, and to back candidates which support that platform. I don’t really understand this idea otherwise… if a dozen Republicans decided to run as democrats to “troll” the primary, you’d want the party to step in, right?
In 2008 Obama was the outsider candidate but he was actually popular enough that the party had no choice but to back him in the end. That’s how the process is supposed to work.
