Yeah you can't hold a "non-binding" primary and then go and retroactively make it count. Same situation as 2008 when J. J. and Hillary Is 44 were arguing to seat the delegates in Florida and Michigan as elected, Michigan being the more absurd of those two. In this case it'd be even more absurd since there's no standard for how delegates would be assigned, so deciding on a delegate allocation method would also be blatantly beneficial toward a certain candidate.
I think the whole reason Missouri had the non-binding primary is it was already scheduled there but would violate RNC rules and be subject to sanctions. So there was an attempt to have it moved forward, but the GOP-controlled State House and State Senate deadlocked, weren't able to meet the deadline, and the caucus had to be set up instead to assign delegates. So basically blame Republicans' inability to govern for this.
Fair enough
