BINGO!
Cruz is loading the rules committee with his delegates and they will put forward changes intended to give him the nomination. However, the new rules will require a vote, not sure how that will work out.
This is exactly what the time & concentration on the delegates is all about.
Likely being orchestrated by Our Principles PAC for Cruz.
Someone alluded to this plan for Cruz on a state party facebook page. It confirmed my suspicions.
