In a normal two year Congress, members introduce somewhere between fifteen and twenty thousand bills and resolutions. The 117th Congress, which ran from 2021 through 2022, saw 17,817 measures introduced and roughly 365 of them signed into law. That works out to a success rate close to two percent. The Congress that followed did even less, finishing with fewer than 300 public laws on the books. Most of the bills that make headlines never get a hearing, never get a floor vote, and never get a number in the statute books. They exist as a press release and a stated position, and then they die quietly when the session ends and every pending bill is wiped clean.
The place most of them die is committee. Every bill gets referred by subject, and the chair of that committee decides whether it is ever scheduled for a markup. If the chair says no, or simply says nothing at all, that is usually the end of it, and there is no appeal. Around nine of every ten bills never leave the committee they were sent to. Some get referred to two or three committees at once, which means two or three chairs each hold a quiet veto over the same text. None of this shows up in any vote count, because ignoring a bill requires no vote at all.
The House has one official escape hatch and it almost never opens. A discharge petition pulls a bill out of committee and forces it onto the floor once 218 members sign it. Since the modern rule took shape in 1931, more than 500 petitions have been filed, and only about two dozen have collected the signatures they needed. Fewer than that ended up becoming law. The reason is not the math, it is the cost of signing. Going around your own leadership in public is expensive, and leadership controls committee seats, subcommittee gavels, and a good deal of campaign money.
The Senate adds its own filter on top of that. Sixty votes are needed to cut off debate on most legislation, so a bill with 55 supporters passes nothing. Any single senator can place a hold, which does not technically block a bill but forces leadership to burn days of floor time to move it anyway. Floor time is the scarcest thing in the building, and the majority leader decides how it gets spent. A bill that clears the House with a strong bipartisan vote can sit untouched for a full session because it was never worth the days it would cost. That call gets made by one person and it never gets recorded anywhere.
What does pass tells you something too. A real share of the public laws in any given Congress rename post offices, name federal buildings, or make technical corrections to statutes already on the books. The substantive policy tends to travel in a handful of very large packages, because bundling is the only reliable way to move anything at all. The annual defense bill and the yearly spending bills become the vehicles that riders attach to, which is why provisions on public land, health programs, and sanctions end up inside a military bill. So a low count of laws does not mean nothing is happening. It means the policy got squeezed into a few votes that almost nobody has time to read in full.
Almost every bill that eventually passes has been introduced before and gone nowhere at least once. Sponsors reintroduce the same text session after session, waiting on a change in committee leadership, a shift in the majority, or a news event that makes the idea suddenly urgent. That is why a bill can look brand new in a headline and carry a ten year history behind it. Cosponsor counts get quoted as proof of momentum, and they are the weakest signal available. A member can cosponsor a bill in an afternoon at no cost, and hundreds do it as a favor or as a message to voters back home. A bill with 200 cosponsors and no scheduled markup is going nowhere.
So when a bill shows up in the news, there are better things to check than the sponsor list. Ask whether the committee of jurisdiction has scheduled a hearing or a markup, because that is the first real gate. Ask whether the chair of that committee has said anything about it in public. Ask whether there is a companion bill in the other chamber, since a House bill with no Senate partner has half a path at best. Ask whether leadership has put it on a floor calendar for the month. Congress.gov posts all of it for free and the answers take about two minutes to find. Most of the time the answer is that nothing has happened, which is the honest status of nearly every bill you will ever read about.
