The process has never worked. I attended a couple caucuses myself between becoming 17 [0] and leaving Iowa. I still hear about them from family. They have various flaws. The most severe one IMHO is that due to the time commitment, they only reflect the voice of die-hards and/or those with few responsibilities. That's true for choosing the candidates and even more so for choosing the platform.

However, I imagine you mean this specific failure mode (unable to produce an authoritative count within X hours for some smallish X) is new. AFAIK, that's correct.

I would love it if this failure inspires them to change to a standard primary process. Probably won't, though.

[0] iirc you can participate if you will be 18 by the general election.
