Florida's 60 Percent Rule and the Amendment That Won a Majority and Lost

On election night in November 2024, the count for Florida's Amendment 4 settled at a number that, in almost any other context in American politics, would be called a landslide. Roughly 57 percent of Florida voters, several million people, had voted to add a right to abortion before viability to the state constitution. The yes vote ran close to the vote total of the winning presidential candidate in Florida. And it lost. Florida requires 60 percent approval for any amendment to its constitution, and Amendment 4 fell about three points short. The state's six-week abortion ban, in effect since that spring, stayed in force. Here is a strange, true detail worth keeping in mind as the story unfolds: the 60 percent rule that defeated Amendment 4 was itself adopted in 2006 by a vote of less than 60 percent.

In short: Florida's 2024 abortion amendment won a solid majority but failed under the state's requirement that amendments get 60 percent. That rule, adopted in 2006, has real arguments on both sides, and how voters judge it should not depend only on whether they like the outcome of any single vote. This post lays out both cases and where I come down.

How Florida got to a six-week ban

Florida had long been a relative haven for abortion access in the Southeast. In 1989, the Florida Supreme Court held that the state constitution's explicit right of privacy, which voters added in 1980, protected abortion. That ruling stood for more than three decades.

After Dobbs, the state moved fast. A 15-week ban signed in 2022 took effect that summer. In 2023, the legislature passed a ban at six weeks of pregnancy, before many people know they are pregnant, with the provision that it would take effect only if the state's courts upheld the 15-week law under the state constitution. On April 1, 2024, the Florida Supreme Court did exactly that, overruling its own earlier precedent and holding that the privacy clause did not protect abortion. The six-week ban took effect on May 1, 2024.

On the same day, the court also allowed Amendment 4 to appear on the November ballot, finding its summary clear enough for voters to understand. So Florida's voters were going to get to answer the question directly. The only question was what counted as yes.

What the six-week law says

Since the stakes of the vote were concrete, it helps to know what the law that survived actually does. This is a general description, not legal advice; the statute and the state health department are the official sources.

Florida's law bans most abortions once cardiac activity can be detected, around six weeks of pregnancy. It contains exceptions. Abortion is permitted to save the pregnant patient's life or to prevent a serious risk of substantial and irreversible physical impairment, generally with certification from physicians. It is permitted for a fatal fetal abnormality before the third trimester, again with physician certification. And it is permitted in cases of rape, incest or human trafficking up to 15 weeks, but only if the patient provides documentation such as a restraining order, police report or medical record.

Supporters of the law say those exceptions cover the hard cases. Doctors and patients' advocates have argued that the language about serious risk is vague enough that physicians hesitate until a patient is in danger, and that the documentation requirement for rape is a barrier for survivors who never went to the police, which is most of them. Those arguments were central to the Amendment 4 campaign.

The law also changed the regional map. Before 2024, Florida had served as a destination for patients from neighboring Southern states with stricter laws. After the six-week ban took effect, that option largely closed, and patients across the region faced longer trips.

Where the 60 percent rule came from

Florida's constitution has been amended many times by citizen initiative, and some of those amendments were mocked as clutter. The best-known example is a 2002 amendment protecting pregnant pigs from confinement in small crates. Critics held it up as proof that the constitution had become a place for policy that belonged in statutes.

In 2006, the legislature put Amendment 3 on the ballot. It required 60 percent voter approval for future constitutional amendments. Supporters, including business groups, argued that the state's founding document should be harder to change than an ordinary law. Amendment 3 passed with roughly 58 percent of the vote, which was enough because it was being judged under the old simple-majority rule.

So the rule that would block Amendment 4 got in under a lower standard than it set for everything after it. That fact does not make the rule illegitimate; constitutions often change their own amendment process by the old rules. But it is a useful reminder that supermajority rules are choices, made by majorities, that bind future majorities.

The campaign and the state's role in it

The Amendment 4 campaign gathered well over the hundreds of thousands of verified signatures needed to qualify. Its opponents included Governor Ron DeSantis, who used his office and state resources against it in ways that drew wide attention. A state agency ran a website and ads critical of the amendment. State officials investigated petition signatures and sent law enforcement officers to some voters' homes to ask whether they had signed. Critics said the state was using public money and police power to campaign against a citizen initiative; the governor said the state was informing voters and protecting the integrity of the petition process.

After the vote, in 2025, Florida enacted a law tightening the rules for petition circulation, including new requirements and penalties for people who gather signatures. Supporters said it was needed to prevent fraud. Critics said it would make citizen initiatives much harder and more expensive, which they argued was the point.

The case for a supermajority rule

Let me make the strongest case for Florida's rule, because it deserves one.

A constitution is not supposed to be a statute book. It sets the framework of government and protects basic rights, and it should not swing with every shift in public mood. The U.S. Constitution itself requires two-thirds of both houses of Congress and three-quarters of the states for an amendment. Many states require legislative supermajorities to propose amendments. A rule that requires broad consensus before changing the framework encourages amendments that unite rather than divide.

There is also an argument from experience. Citizen-initiated amendments can be written by well-funded interest groups, financed heavily from outside the state, and passed in a single election with limited debate. Once in the constitution, they can only be undone by another amendment. A 60 percent threshold asks for a margin of support that suggests durable agreement, not a temporary majority.

And there is consistency. Florida's rule applies to every amendment, on every subject, regardless of which side benefits. It has blocked measures conservatives liked as well as ones progressives liked. A principled supporter of the rule can say it treats all comers the same.

The case against it

Now the other side, which I find more persuasive. This part is opinion, and I want to be clear about why I hold it.

First, a supermajority rule is a minority veto. When 57 percent vote yes and 43 percent vote no, the 60 percent rule hands victory to the 43. Every supermajority rule does this by design, and sometimes that is appropriate. But it is a large thing to do to a direct vote of the people, and it needs a strong justification on the specific subject at hand.

Second, citizen initiatives exist to give voters a way around their legislature when the legislature will not act or acts against majority opinion. In Florida, a legislature had passed a six-week ban; public polls generally found that most Floridians supported greater access than that. The initiative was the only tool a majority had. Making that tool require 60 percent means the legislature's choice prevails even when a clear majority disagrees.

Third, the pig-crate argument cuts both ways. If the concern is policy clutter in the constitution, the better solution is a separate route for statutory initiatives, which Florida does not offer for citizens. Without one, voters who want to change policy over a legislature's objection have only one door, and the 60 percent rule narrows it.

Fourth, a supermajority requirement on amendments was applied here to a question about personal rights, the very kind of thing constitutions are meant to protect. The Florida privacy clause that once protected abortion was adopted in 1980 by majority vote. The state supreme court read it differently in 2024. The voters' attempt to restore that protection was held to a higher standard than the protection itself ever was.

I think a reasonable middle position exists. A state might require broader support for amendments proposed by the legislature itself, or require amendments to pass in two consecutive elections, as Nevada does, rather than demanding 60 percent in one. Those designs protect stability without letting a determined minority hold a lasting veto.

How other states set the bar

Florida is not alone in asking for more than a simple majority, but its rule is among the strictest for a citizen initiative, and the variety elsewhere shows how many choices a state has.

Colorado adopted a rule in 2016 requiring 55 percent approval for most constitutional amendments, along with a requirement that petition signatures come from every state senate district. Colorado's 2024 abortion measure cleared that bar. Nevada takes a different approach: an initiated constitutional amendment must pass in two consecutive general elections, which slows change down without demanding a supermajority in either vote. Illinois requires either 60 percent of those voting on the amendment or a majority of everyone voting in the election, which in practice means a measure can fail even when it wins most of the votes cast on it, because many voters skip ballot questions. New Hampshire requires two-thirds of those voting for amendments the legislature sends to voters, and it does not have a citizen initiative at all.

Many states, including Ohio, Michigan, Missouri, Arizona and California, require only a simple majority. In Ohio, the legislature asked voters in August 2023 to raise the threshold to 60 percent, and voters said no. Arizona voters, by contrast, agreed in 2022 to require 60 percent for initiatives that raise taxes, which shows that voters sometimes accept supermajority rules when they are targeted at a specific kind of measure.

There is no single correct design. What the comparison shows is that the threshold is a choice that shapes outcomes as much as any campaign does. A 57 percent vote passes in Colorado and Ohio. It fails in Florida. The same voters, making the same choice, would get opposite results depending on where they live.

That is one reason I think debates about thresholds should take place apart from any particular measure, and with the question asked plainly: how large a majority should it take to change the constitution, and how should that differ between rules about government structure and protections for individual rights?

Results under the rule that cut the other way

It is worth noting that Florida voters have cleared the 60 percent bar for things progressives championed. In 2018, Amendment 4 of that year restored voting rights to most Floridians with past felony convictions, passing with about 64 percent and drawing support across party lines. In 2020, voters approved a gradual increase in the state minimum wage to 15 dollars an hour, passing with just over 60 percent.

Both of those measures were sold to voters as matters of fairness rather than party. The voting rights amendment was championed by people who had themselves served sentences, and its campaign talked about second chances and redemption in language that resonated with churchgoers and conservatives. The wage measure was framed around work and dignity. Neither campaign asked voters to become progressives. They asked for agreement on one question. The abortion campaign tried the same approach, stressing doctors and government interference, and came within a few points of the bar. Whether a different message could have closed that gap is a fair question that nobody can answer with certainty.

These results show two things. A broad, cross-party message can clear a high bar in Florida. And even popular progressive measures can face trouble after they pass. The legislature required people with felony convictions to pay all outstanding fines and fees before their voting rights were restored, a condition that has kept many people from voting and that federal courts allowed to stand.

What you can do

Florida's story is about abortion and about the rules for direct democracy. Both are within reach of ordinary voters.

• Look up the minimum wage that 2020 vote created. The minimum wage page shows every state's current rate, including Florida's schedule, and it is a good conversation starter about what initiatives can win.
• Learn how voting rules are being rewritten. The voting rights and redistricting page covers the laws that decide who votes and how, including new limits on petition drives.
• Follow the abortion measures still to come. The abortion on the ballot page tracks proposed amendments and petition campaigns in each state.
• Make sure you and the people you know can vote. The voting page lists registration deadlines, ID requirements and mail and early voting options for every state.
• Ask your state legislators what they think about thresholds. The representatives lookup shows them and their latest votes; ask whether they would support raising or lowering the bar for citizen initiatives, and why.
