Florida's primary is screwy. Think about it.
The candidate that over half the voters DIDN'T want, got all the delegates.
They should have had a runoff.
The ideal plan would be to do runoffs until a candidate have a majority, or even greater, of the votes.
Each run off you eliminate the lowest vote getter and see who those voters supported.
Problem is there is no time to schedule a new ballot, get them printed and anything else that might be required.
Maybe a ballot where you number your choices....if your first choice doesn't make the cut, they know who your second choice is...and your third. When you run out of candidates you can support, no one gets your vote.
I guess "None of the Above" would be where to put your vote as your last choice. If, after all the runoffs, "None of the Above" has the majority, no one gets the nod.
