Section One

Neither Snow nor Rain:
251 Years of American Mail

The story of the United States Postal Service begins before the nation itself. In 1775, the Continental Congress appointed Benjamin Franklin as the first Postmaster General, recognizing that a reliable mail system was as essential to the revolution as muskets and powder. Franklin and the founders understood something remarkable: a democratic nation spread across a vast continent could only survive if its citizens could communicate freely, cheaply, and reliably.

What they built became the most ambitious postal system in human history. By the 1830s, Alexis de Tocqueville marveled that America had more newspapers than any country on earth — a direct consequence of cheap postal rates that made information flow to the frontier as easily as to Philadelphia. The USPS delivers more mail every single day, per capita, than most countries deliver in a month. Only five nations — Brazil, France, Germany, Great Britain, and Japan — manage to deliver in an entire month what the USPS handles in a single delivery day.

No other country has quite the same model. The USPS is constitutionally empowered (Article I, Section 8), mandated to serve every address in the nation at uniform rates — from a penthouse in Manhattan to a houseboat on the Kenai Peninsula — six days a week. It is the only carrier legally obligated to provide universal service at affordable, uniform prices. Other countries have universal service obligations, but the U.S. framework is uniquely broad and uniquely unbacked by direct taxpayer funding: the USPS is self-financing, generating revenue almost entirely from postage and services.

The Postal Service shall have as its basic function the obligation to provide postal services to bind the Nation together through the personal, educational, literary, and business correspondence of the people.

— 39 U.S. Code § 101

The Smithsonian's National Postal Museum, housed in the 1914 City Post Office building beside Union Station, makes all of this tangible. Its 90-foot atrium suspends three vintage airmail planes overhead alongside an 1851 stagecoach, a 1931 Ford Model A postal truck, and a reconstructed Railway Mail Service car. The permanent exhibitions — Binding the Nation, Systems at Work, Moving the Mail, Mail Call, and Customers & Communities — walk you from colonial post roads through pneumatic tube networks under city streets to ZIP codes and optical scanners.

The William H. Gross Stamp Gallery, the largest in the world, houses nearly six million items — including one of the four surviving blocks of the legendary Inverted Jenny, a proof of the 1765 Stamp Act, and the mailing wrapper that carried the Hope Diamond to the Smithsonian in 1958 (yes, Harry Winston just… mailed it). There's Owney, the scruffy mutt who became the beloved mascot of the Railway Mail Service in the 1880s, traveling by mail train across the country collecting tags from every stop. The museum is free, it's magnificent, and it tells the story of the infrastructure that made American democracy function.

The USPS Under Siege:
Why It Matters Now More Than Ever

The Postal Service faces an existential convergence of threats in 2025–2026 that would have been unimaginable to Franklin. Understanding them is essential to appreciating what we risk losing.

The Amazon Problem

Amazon is the USPS's single largest customer, providing over $6 billion in annual revenue — roughly 7.5% of the agency's total income. Amazon's contract with the Postal Service expires in October 2026, and the e-commerce giant is actively building out its own last-mile delivery network, having already invested over $4 billion in rural expansion and its Delivery Service Partner program. Reports indicate Amazon plans to cut at least two-thirds of its USPS parcel volume by late 2026. In 2025, Amazon surpassed the USPS to become the largest parcel carrier in the United States, delivering 6.7 billion packages to the USPS's 6.6 billion. The Postal Service posted a $9 billion net loss in fiscal 2025, and Postmaster General David Steiner has warned Congress the agency could run out of cash by fall 2026. The loss of Amazon's business would be devastating, particularly in rural communities where no private carrier matches the USPS's reach.

The Tariff Tangle

In August 2025, the Trump administration ended the de minimis exemption that had allowed international packages valued under $800 to enter the U.S. duty-free. International mail volume into the United States collapsed by 80% virtually overnight. The USPS was caught in the confusion — in February 2025, then-Postmaster General Louis DeJoy announced the agency would stop accepting parcels from Hong Kong and China, only to reverse course twelve hours later. The agency has since launched a "Delivered Duty Paid" service allowing shippers to prepay import charges, but the disruption to international mail operations has been profound, with 88 global postal operators temporarily suspending or restricting service to the U.S.

The Ballot Box: Watson v. RNC

On March 23, 2026 — just two days ago — the Supreme Court heard oral arguments in Watson v. Republican National Committee, a case that could fundamentally reshape mail-in voting in America. At issue is whether federal statutes from the 1800s establishing "Election Day" require all mail ballots to be received by election officials by that day — not merely postmarked. If the conservative majority rules as signaled during argument, it would invalidate grace-period laws in 14 states plus D.C., affecting tens of millions of mail voters. Nearly four million military servicemembers and overseas citizens rely on the mail to vote. Washington State, an entirely vote-by-mail state, would see its 21-day grace period eliminated. The implications for voter access — particularly for soldiers, elderly citizens, people with disabilities, and rural Americans who depend on the Postal Service — are staggering. A decision is expected by late June.

Why This Matters

The USPS is not a business. It is infrastructure — as fundamental as highways and bridges. It is the only delivery service constitutionally mandated to reach every American, regardless of profitability. It binds the nation across 167 million delivery points, six days a week. It is how rural pharmacies receive prescriptions, how small businesses ship products, how Social Security checks reach seniors, and how citizens exercise the right to vote. The museum on Massachusetts Avenue tells the story of 251 years of that promise. The question facing us now is whether we intend to keep it.
