Meaning the current DNC won't work against a candidate willing to disclose all of it.
I kinda feel like this is giving 'em a little too much credit. However, I can't argue with your overall argument, nor the logic you present to get there.
That said, the general nature of the problem hasn't changed. The blatant corruption that is directly enabled by the vile (and, in my not so humble opinion, treasonous) Churches United ruling has redefined the playing field. Basically, only the corrupt have any realistic chance of election nationally, which completely undermines the democratic part of our government. (And yes, democracy only plays a part in a republic style government. The US has never been a "democracy".)
My own takeaway is to focus my attention more on local elections. They have always been far more important than most people realize (myself included), now even more so. If there's any chance of reversing the terrible damage being wrought, it starts locally. This is true whether you believe in working with, or against, the current system.
And again, this isn't meant as an attack on your own argument. I knew about the change in DNC leadership, but I've been overlooking both it's potential significance, as well as that of the current media framing - specifically the lack of "only other option" type statements. Thank you for your perspective!
Edit/P.S. The reaction to David Hogg's actions are a good example of why I continue to be skeptical of the DNC. On the other hand, what else could anyone expect, really. That man has definitely piqued my curiosity, though, and I hope we see more from him down the line.
