The Veto Is the Constitution’s Most Libertarian Power—and Congress Made It Meaningless

Every power the federal government exercises is, at bottom, a power to do something. It can spend, regulate, tax, prohibit, subsidize, and command. But there is one constitutional authority designed to do nothing except stop government in its tracks. It cannot spend a dollar. It cannot hire a single bureaucrat. It cannot create a program or write a regulation. Its only function is to say no.

A Brake, Not a Weapon

That is the presidential veto. It is, in the truest sense, the Constitution's most libertarian tool. Yet Congress has spent decades quietly making the veto meaningless. Not by overriding presidents more often, but by writing laws so enormous, so urgent, and so entangled that no president can realistically refuse them.

Article I, Section 7 of the Constitution is plain. Every bill that passes the House and Senate must be presented to the president. If he approves, he signs it. If he does not, he returns it with his objections to the house where it originated. That is the whole mechanism. The president may accept the entire bill or reject the entire bill. He cannot amend a line. He cannot strike a paragraph and keep the rest.

Alexander Hamilton explained the design in Federalist 73. The veto establishes "a salutary check upon the legislative body, calculated to guard the community against the effects of faction, precipitancy, or of any impulse unfriendly to the public good." Notice the words Hamilton chose: faction, precipitancy, impulse. The Founders did not fear a slow, deliberative Congress. They feared a majority that got carried away, passed something reckless, and trampled individual liberty before anyone could catch their breath.

The veto was not meant to be a routine policy tool. It was a brake. George Washington, who understood that executive restraint was part of the job, used it twice in eight years. He did not see the presidency as a third legislative chamber. Neither did his successors. The veto's value was never in how often it was used, but in the fact that it existed. Congress had to think twice before sending the president a bill it knew he could publicly reject.

The Un-Vetoable Bill

Here is what has happened in plain sight. Suppose a senator wants a few million dollars for a pet project. A bridge to nowhere, a grant program nobody asked for, an earmark that would never survive a floor debate on its own. No problem. Bury it in a 2,000-page omnibus spending bill that also funds the military, border operations, veterans' hospitals, and disaster relief. Then drop that bill on the president's desk two days before government funding runs out.

What is the president supposed to do? Veto the entire thing over one corrupt line buried on page 1,437? Shut down the government and stop paying the troops because Congress hid an indefensible earmark inside a must-pass bill? Of course not. He signs it, issues a statement complaining about the parts he does not like, and the republic moves on.

That is not an accident. That is a strategy. Modern Congress, both parties, has learned to make its signature bills un-vetoable by design. Continuing resolutions, omnibus appropriations packages, debt-ceiling suspensions, reconciliation bills. These are all variations on the same trick. Take hundreds or thousands of separate decisions, stuff them into one colossal bill, and present the president with a false choice between approving the whole thing and causing an immediate crisis.

The numbers tell the story. Franklin Roosevelt vetoed 635 bills over his presidency. Harry Truman vetoed 250. Dwight Eisenhower vetoed 181. Modern presidents, by contrast, have issued a dozen or so vetoes in a typical four-year term. That is not because they suddenly began agreeing with Congress. It is because Congress stopped sending them clean, vetoable bills.

Accountability Disappears

The beauty of the veto is not merely that it stops bad laws. It is that it forces one person to accept responsibility for stopping them. When the president vetoes a bill, he must put his reasons in writing. The country sees the bill, sees the president's objections, and can judge whether he acted on principle or politics. That transparency disciplines both branches. Congress is less likely to pass indefensible bills, and the president is less likely to veto defensible ones.

But when Congress packs a thousand legislative decisions into one omnibus, no one is responsible for any of them. The president signs the bill and blames Congress for the parts he did not like. Congress blames the president for signing it. The bureaucrats who actually spend the money never stood for election. The ordinary citizen is left holding higher prices, a larger debt, and no one to vote against.

John Adams told us the American republic was to be a government of laws, and not of men. The modern omnibus has become a government of neither. It is a government of unread pages.

Henry Hazlitt taught us to look for the seen and the unseen. The seen benefit of an omnibus is easy to identify. The government stays open, paychecks go out, and no one has to suffer the inconvenience of a shutdown. That benefit is immediate and visible. The unseen cost is far greater. Every time Congress puts a bad idea inside a must-pass bill, it teaches every future bad idea to do the same. Every lobbyist learns that the way to win is not to persuade the public, but to get a line into a bill that cannot be stopped. Every member of Congress learns that the way to avoid a difficult vote is to hide the difficult vote inside a package large enough to overwhelm the veto.

That is how liberty is lost. Not in one dramatic vote, but in thousands of pages nobody read.

Friedrich Hayek's knowledge problem applies here with brutal force. No member of Congress, indeed no committee of members, can possibly know what is in a 3,000-page bill passed in a matter of hours. The people who do know what is in the bill are precisely the people who wrote their own favors into it. The rest of the legislature votes on a document it has not read, and the president signs a document he cannot veto. That is not deliberation. That is the opposite.

The Wrong Fix

Some will say, fine, give the president a line-item veto. Let him cut the bad parts while signing the rest. I understand the frustration, but that is not the answer under the Constitution as written. Article I says the president approves or returns every bill, the whole thing. He cannot selectively edit legislation after it reaches his desk. In 1998, the Supreme Court struck down the Line Item Veto Act on precisely these grounds. The Court held that it violated the Presentment Clause by effectively allowing the president to rewrite a law after Congress passed it.

Whatever one thinks of that decision, the structural concern is real. A president with a red pen becomes a legislator, not an executive. He could pick winners and losers within a bill, rewarding political allies and punishing enemies. That is not a check on Congress. It is another form of unaccountable power.

The real problem is not that the president lacks the power to veto lines. It is that Congress has stopped presenting him with lines to veto.

Restoring the Shield

Many state constitutions require a single-subject rule. No rider can be attached to an unrelated bill. If a legislature wants to fund a bridge, the bill must be about that bridge. It cannot be welded to the defense budget or hidden inside a continuing resolution. The House and Senate should adopt and enforce the same rule for themselves. In the long run, we should consider a constitutional amendment requiring it.

This would restore the veto to what the Founders designed. It would make each bill small enough to read, specific enough to debate, and clean enough to veto. Congress would have to vote on the actual merits of each spending item, or at least bundle related items in a way the public can follow. The president would regain the ability to say no without shutting down the government. And the American people would regain the ability to hold someone accountable.

Will this cause gridlock? No. It will cause deliberation. A constitutional republic is supposed to deliberate. It is supposed to be slow. It is supposed to make it hard to pass bad laws. The Founders were not trying to build an efficient machine. They were trying to build a free one.

The veto is not a relic. It is a shield between the ordinary citizen and a legislature that always wants to do something. Spend more, regulate more, control more. Congress has not abolished that shield. It has simply learned to walk around it. The fight to restore the veto is a first-principles fight for limited government, personal responsibility, and the Constitution as written. The Constitution already gives us the tool. What we need is a Congress willing to stop picking the lock.
