Pop quiz. Ask ten random Americans on the street what “bicameral” means and watch what happens. A few will nail it. A few will guess it has something to do with cameras. Most will just stare at you like you asked them to conjugate Latin. And that is the real problem underneath the current fight over the Democratic Socialists of America’s push to scrap the Senate and turn Congress into a single chamber. This is not just a policy debate. It is a test of whether Americans still understand the machine their own government runs on. Judging by the blank stares, common sense is not so common anymore. So let’s fix that, one history lesson at a time.
What Bicameral Actually Means
Bicameral simply means a legislature split into two chambers. In the United States, that is the House of Representatives and the Senate. Both have to agree, in the same form, before a bill becomes law. It sounds almost boring when you say it that plainly. It is not boring. It is one of the most deliberate design choices in the entire Constitution, and it did not come out of nowhere.
The idea has roots stretching back to the British Parliament, split between the House of Commons and the House of Lords, one representing the common people and one representing the aristocracy. The American colonies largely copied this two-house model in their own legislatures well before independence. So when the Founders sat down in Philadelphia in the summer of 1787, bicameralism was not some abstract theory. It was the system most of them had already lived under.
Here is the twist most people never learn in school. Immediately after independence, the young United States tried the opposite approach. Under the Articles of Confederation, from 1781 to 1789, the national government was a single-chamber Continental Congress with no president, no national courts, and barely any power to tax or enforce its own laws. It was, to put it plainly, a mess. States ignored national requests for money. Congress could not respond effectively to Shays’ Rebellion in Massachusetts. The whole experiment in unicameral national government nearly sank the country before it had even properly floated. That failure is exactly why fifty five delegates showed up in Philadelphia in 1787 to start over.
At the Constitutional Convention, two competing plans for a new legislature nearly wrecked the whole project before it started. The Virginia Plan, championed by James Madison, proposed representation based on population, which delighted large states like Virginia and terrified small ones like Delaware and New Jersey. In response, the New Jersey Plan proposed equal representation for every state regardless of size, which delighted the small states and terrified the large ones. The convention was deadlocked through the brutal heat of a Philadelphia summer with no air conditioning, which honestly explains a lot about everyone’s mood.
The fix was the Connecticut Compromise, sometimes called the Great Compromise, engineered largely by Roger Sherman and Oliver Ellsworth of Connecticut. It split the difference. The House would be based on population, giving the people direct proportional say. The Senate would give each state two votes regardless of size, protecting smaller states from being steamrolled by their bigger neighbors. Two chambers, two different logics of representation, one built in check on the other. That is the deal that saved the Constitutional Convention, and it is the deal the DSA now wants to unwind.
What Unicameral Actually Means
A unicameral legislature has just one chamber. One vote, one body, done. Today, Nebraska is the only state in the country with a unicameral legislature, adopted in 1937 after Senator George Norris campaigned for it, arguing a single nonpartisan chamber would be cheaper and less prone to backroom conference committee deals. It is a genuinely interesting experiment, worth studying on its own terms.
But context matters enormously here, and any honest history lesson has to include it. Plenty of stable democracies around the world, including Denmark, Sweden, New Zealand, and Israel, operate with unicameral national legislatures and do just fine. The catch is that those are typically small, unitary parliamentary systems without America’s specific architecture of a large federal republic made up of fifty sovereign states with wildly different populations and interests. Comparing them to the American system is comparing apples to a very different orchard. The American Senate was not designed just to slow things down for the sake of it. It was designed specifically to protect the federal bargain between states of different sizes, a problem most unicameral parliamentary democracies never had to solve in the first place.
What Madison, Hamilton, and Jay Actually Said About This
This is where the DSA’s proposal runs headlong into the actual text the Founders left behind, not vibes about the Founders, the actual essays.
James Madison made the case for bicameralism directly in Federalist No. 62, writing that the necessity of a Senate is shown by “the propensity of all single and numerous assemblies to yield to the impulse of sudden and violent passions, and to be seduced by factious leaders into intemperate and pernicious resolutions.” Translation: a single chamber is a mob with a gavel. Madison argued a second chamber “doubles the security to the people” because any scheme of usurpation now needs two separate bodies to agree, not just one worked up crowd of representatives fresh off an election high.
In Federalist No. 51, Madison went further, laying out the entire philosophy of American government in one memorable line: “Ambition must be made to counteract ambition.” He explained that because “in republican government, the legislative authority necessarily predominates,” the remedy is to “divide the legislature into different branches” so they check each other by design, not by good faith. A unicameral Congress deletes that internal check entirely. There is no second body to counteract the first. There is just the first, unchecked.
Alexander Hamilton made a parallel argument in Federalist No. 71, warning against government structures that cave to “temporary delusion” instead of giving the public’s representatives room for “cool and sedate reflection” before acting. A single chamber, especially one designed explicitly around speed and proportional passion as the DSA has proposed, is engineered to do the opposite of what Hamilton wanted. It is built for velocity, not reflection.
And John Jay, writing in Federalist No. 2 through No. 5 about the dangers of a weak, poorly structured union, argued that Americans were “one united people” who needed a government strong enough to hold the country together without collapsing into the factionalism and instability that plagued weak confederations. Jay was not writing about the Senate specifically, but his broader point stands: a government stitched together carelessly, without deliberate checks, invites exactly the kind of instability the Founders spent all summer in Philadelphia trying to avoid.
Where the DSA Actually Stands
This is not a hypothetical fight. DSA co-chair Megan Romer has publicly called for abolishing the Senate, describing it as an outdated institution, and has said the goal is to expand Congress but restructure it into a single proportional chamber, paired with scrapping the presidency for a parliamentary system. That is not a minor structural tweak. That is a full rewrite of the constitutional bargain struck in 1787, the one that convinced small states to sign on to the Union in the first place.
Strip away the modern branding and the DSA is proposing something the country already tried once, under the Articles of Confederation, and already discarded because it did not work. The Founders did not stumble into bicameralism by accident. They built it after watching a unicameral national government nearly fail, and they defended it in writing, essay by essay, against exactly the kind of objections being raised again today.
Every generation gets a chance to relearn why the system was built the way it was. Civics class used to cover this. Apparently it is our turn again. Before anyone signs onto abolishing the Senate, they might want to read the essays the people who actually built it left behind. Common sense used to be common. Consider this the refresher course.
