The solution to this problem will be very simple. The party can change the rules. All delegates will be required to pay a poll tax and to take a literacy test before they will be allowed to vote. If they get past that, there is always a line of snarling dogs and firehoses to get past. Hillary has the matter under control.
Actually, a better solution to the uninformed voter issue is for the IRS to issue a “net tax payer” card.
This card says that (taxes paid - entitlement benefits received) > 0. Then you can vote.
