If you’d like some facts to go with your hyperbole, there are over 8,000 Delegates and Alternates, selecting among 605 candidates to seat 13 Delegates and 13 Alternates.
Those 8000 Delegate were each elected at lower assemblies.
If you believe those 8000 are bought and paid for, that’s your problem, but its not reality.
It’s a bullcrap, anachronistic, method. We started primaries in 1910 and 1912 to end smoke filled rooms. It’s been over a hundred years. The parties’ position (not platform but sanctity) is enshrined in much local, state and federal law. Given all those protections, promoting anything un-democratic is baloney.
