Other states couldn’t care less what the Iowa constitution says on the matter. In practice it’s ultimately up to the DNC (this is a party process after all). In the past if a state threatened to disobey the party the party would just say the state’s delegates wouldn’t count or would count for less. Iowa’s constitution has no governance over DNC policies and practices which at the end of the day are a private matter.
