The Bill of Rights Has a Missing Amendment

Most Americans know the Bill of Rights as ten amendments. It was proposed as twelve.

Two of the original twelve did not ratify with the others in 1791. The twelfth, prohibiting Congress from giving itself a mid-term pay raise, sat dormant for 203 years before ratifying in 1992 as the 27th Amendment.¹ A University of Texas student named Gregory Watson discovered it, started a letter-writing campaign, and got it ratified for under $6,000.²

The tenth has been waiting since 1789.

Formally titled "Article the First," the Congressional Apportionment Amendment set a constitutional limit on how many citizens each House member could represent, and whether that limit would be guaranteed by the Constitution or left to Congress to manage as it saw fit.

The Text

After the first enumeration required by the first article of the Constitution, there shall be one Representative for every thirty thousand, until the number shall amount to one hundred, after which the proportion shall be so regulated by Congress, that there shall be not less than one hundred Representatives, nor less than one Representative for every forty thousand persons, until the number of Representatives shall amount to two hundred; after which the proportion shall be so regulated by Congress, that there shall not be less than two hundred Representatives, nor more than one Representative for every fifty thousand persons.³

Three tiers: one representative per 30,000 people until there are 100 representatives; one per 40,000 until there are 200; then a permanent floor of one representative for every 50,000 citizens, with no upper limit on the total size of the House.

At the current U.S. population of approximately 335 million, the final tier would require a minimum of 6,700 representatives.⁴ Congress has 435, a number it set by statute in 1929 and has not revisited since.⁵

Why the Founders Cared

The Constitutional Convention of 1787 set the initial ratio at one representative per 40,000 people. George Washington, who maintained near-total silence on every substantive question at the convention, broke that silence exactly once.

On the final day, Washington rose to argue the ratio was too high and asked the delegates to lower it to one per 30,000. They agreed unanimously. Historians record it as the only time Washington voiced an opinion on any substantive issue debated at the convention.⁶

James Madison, writing in Federalist No. 55 to persuade New York to ratify the Constitution, acknowledged both sides of the problem. Too few representatives, he granted, and "so small a number of representatives will be an unsafe depositary of the public interests." Too many, and "the number ought at most to be kept within a certain limit, to avoid the confusion and intemperance of a multitude."⁷ Madison believed the House of 65 would grow, as it did. He wrote nothing anticipating a permanent cap.

The Anti-Federalists were less sanguine. Melancton Smith, at the New York ratifying convention in 1788, made the case plainly: "We certainly ought to fix, in the Constitution, those things which are essential to liberty."⁸ Without a constitutional floor on House size, Smith and others argued, nothing would stop Congress from letting districts expand until ordinary citizens could no longer compete for seats against candidates who could afford to reach hundreds of thousands of people at once.

How It Fell One State Short

Congress approved Article the First on September 25, 1789, alongside the rest of what became the Bill of Rights, and sent it to the states.⁹ Ratification required eleven states, three-fourths of the fourteen then in the Union.

Between 1789 and 1791, ten states ratified: New Jersey, Maryland, North Carolina, South Carolina, New Hampshire, New York, Rhode Island, Pennsylvania, Virginia, and Vermont.¹⁰ Connecticut's two legislative chambers deadlocked. The count stood at ten, one short of the threshold.

In June 1792, Kentucky joined the Union as the sixteenth state, raising the required threshold from eleven to twelve. Kentucky ratified, but the new denominator canceled the gain. The count stayed one short.

No state has ratified since. The amendment has never been withdrawn or formally rescinded. It remains pending.

One claim about the ratification count is contested. Eugene LaVergne, a New Jersey attorney, argued in a federal lawsuit that Connecticut had in fact ratified, but that its records had been lost in archives rather than reflecting a genuine failure to act. If true, the pre-Kentucky count would have cleared the eleven-state threshold. Federal courts rejected the case.¹¹ Archivists have not independently confirmed LaVergne's reading of the Connecticut records.

What Buried It: The 1929 Act

The story of Article the First cannot be told without the Permanent Apportionment Act of 1929.

After the 1920 census documented a massive population shift toward cities, rural-dominated Congresses refused to reapportion for a decade, in direct violation of the constitutional mandate to reapportion after each census. When they finally acted, the result was the 1929 Act: a statute capping the House at 435 members, with no constitutional amendment, no referendum, and no public mechanism for challenge.⁵

That cap has held for 96 years. The population has tripled.

The 435-member cap is not in the Constitution. It is a statute Congress passed about itself. An ordinary act of legislation can change it; a ratified constitutional amendment supersedes it entirely. Most people assume the size of the House is a founding-era fixture. It is not.

What Ratification Would Change

Gerrymandering

Small districts are harder to gerrymander than large ones. David Speiser, writing in Astral Codex Ten, documents this with North Carolina's 2024 results: "50.9% of people voted Trump, 60% of state senate seats are held by Republicans, and 71.4% of their House seats belong to Republicans." He notes that the state senate, with 50 seats, is "only half as gerrymandered as the House delegation" with 14 seats. Congressional districts drawn from pools of 50,000 people behave more like state legislative districts, where partisan distortion runs measurably lower.²

Money

A congressional race in a 50,000-person district costs a fraction of what it costs in a 760,000-person district. Candidates can canvass on foot; local reputation carries weight that advertising cannot simply purchase. The return on large donations also changes: spread across 6,700 competitive races instead of 435, a million dollars buys a much smaller share of the outcome.

Accountability

David Ernst calculated in 2017 that the average congressional district contained 711,000 constituents.¹² A representative serving that many people cannot hold a town hall the district could actually fill, or respond personally to constituent mail at that volume. The community is too large to organize around a single race. At 50,000 constituents, the founders' intended ceiling, the arithmetic of accountability changes.

Where Things Stand

Thirty-eight states must ratify. Ten are on the books from 1789 to 1792. Twenty-eight more are needed.

The 27th Amendment required thirty-eight ratifications as well, starting from nothing, on a proposal nearly two centuries old that almost no one had heard of. Gregory Watson got it done in ten years with $6,000 and a letter-writing campaign.²

Article the First starts with ten states already recorded and a constitutional argument stronger than Watson's.

Please consider writing letters to your state congresspeople; it is very likely they represent a state that did not exist when the constitution was written. If you feel like it, subscribe for updates on the ratification effort. This page is open to edits via GitHub.
