America conducts most of its elections by awarding the winner to the candidate who gets the most votes even if a majority of the people cast ballots for someone else. We’re used to this and people don’t question it as much as they should. It creates all kinds of problems and discourages third party voting. Ranked-choice voting has been adopted in Maine to deal with this, and some states opt for run-off elections if no one reaches a majority.

The Democratic National Convention does not operate by our ordinary rules. To be awarded the nomination, a candidate needs a clear majority of the votes. On the first vote, the delegates will be pledged to a candidate, but thereafter they are free to choose someone else. Also, if there is a second vote, the superdelegates (party and elected officials) get to weigh in.

This is not exactly like ranked choice voting, and it’s not a strict run-off either as no one is eliminated after the first vote. But it offers the opportunity to discover who actually has the most support from the delegates.

Simply having the most votes going into the convention doesn’t tell us much about this since a simple plurality is technically a minority.

On Twitter, I tried to give an example of what I’m talking about. Imagine that you’re the elected sheriff of a small frontier town in the 19th Century and you have finally apprehended the horse thief. The people are joyous but also divided about what kind of punishment should be doled out. You want to please the people and win reelection, so you ask them whether the horse thief should get the death penalty or some lesser punishment. To your surprise, 70 percent of the townsfolk recommend some leniency while 30 percent want him dead.

It would make sense to accept this verdict and begin a debate about a suitable non-lethal sentence, but what if instead you offered four options: hanging, jail, hard labor or a fine?

Now imagine that the same 30 percent opted for the hanging, but the other three options were split at around 23 percent.

Should you hang the bastard because more voters chose that option than any of the others? Do you think this would please the people and make them more likely to reelect you?

The problem was introduced when you didn’t drop the death penalty as an option. This set you up to settle on an unpopular position.

Choosing candidates is not binary like being for or against the death penalty, but neither does it confer any natural credibility to have the most votes among many options if most of the people have voted for someone or something else.

We tend to think it makes sense that the person with the most votes should win because that’s how we ordinarily operate, but it’s not uncommon for someone to lose an election in our country because a third party candidate cannibalized their votes. A Republican who wins a blue district because the Green Party candidate pulled 10 percent of the vote is not in a better position to win a one-on-one race. If they won according to the rules, we accept that, but the Democratic National Convention does not operate by those rules.

A Democrat who isn’t even supported by a majority of their own party is not necessarily going to be a better position than other candidates to beat Donald Trump. One can argue that denying the winner of a plurality the nomination would be divisive and cost the alternative the party unity needed to win, but you can just as easily argue that nominating someone who cannot command a majority within the party will have the exact same problem.

At the Nevada debate on Wednesday, every candidate except Bernie Sanders refused to commit to supporting a plurality winner. Collectively, they have won over 70% of the votes so far in Iowa and New Hampshire, but only Buttigieg has accumulated more delegates than Sanders. As I said above, this isn’t a binary pro- or anti-Sanders vote. It wouldn’t be fair to say that 70% oppose Sanders or that anyone else has more support than he does. To determine that, you need to get down to second choices.

Imagine asking a Buttigieg voter who they prefer if Buttigieg isn’t the candidate, and then when they tell you ‘Klobuchar,’ you respond by saying you can’t pick her because Sanders got more votes. That would’t be a fair way of measuring voter sentiment. But that’s what a lot of people think needs to happen if no one gets a majority before the convention.

According to the rules, the people get to choose the nominee rather than party bosses, but if the people don’t produce a majority winner, then it is up to the delegates to agree on someone. The best way for them to do that is to express their true preference rather than defer to the person with the most votes. We wouldn’t want to see a hanging just because the delegates couldn’t agree on a lesser punishment and we shouldn’t believe that kind of process will please the townsfolk and find the best candidate to beat Trump.
