The implicit and critical part of this 'chaos' is decentralization and localism. When every caucus is run differently and by local organization, that's not easier to game. The only way to game that kind of system is to centralize and standardize the process ... which is exactly what is happening.

Who cares! Every person will have different motives for doing what they are doing. That's expected. Welcome to Democracy.
Russian troll farms drove nice wedges across the US on all kinds of issues (by boosting the extreme viewpoints) and it worked wonderfully despite there being no central/standardized process.
Caucuses are impacted by that just as much as any other process.
It's a mistake to think all competitors want a competitor they can trick into helping them. What if they just want to see their competition crumble?
