Ballot order does make a difference. This has been understood from time immemorial. If I had any confidence that a neutral rule would be adopted and applied impartially, I would say fine. But … the moment the democrats have complete control in Florida, they will move to reinstitute the preference for the governor’s party. They will probably do so on the grounds that a rotating system is confusing to voters. And an activist judge will agree. The rule in play here is not neutrality. The rule is that whatever the democrats want to game the system for themselves will be awarded by a judge.
How utterly stupid can people be? If I were in charge, a lot of people (of whatever party) would be turning in their voter registration cards, because they don't deserve them.
