Two members of Congress right now have been in office for 51 years. Fifty-one. That's longer than most Americans' entire working lives, longer than the average marriage, longer than some countries have existed in their current form. Chuck Grassley and Ed Markey both arrived in Congress back in 1975 and never left. This isn't a one-off fluke either. It's a pattern that runs straight through the institution, and once you see the numbers, you can't unsee them. Somebody who was in diapers when these two took office has since grown up, had a career, maybe raised kids of their own, and watched both men still show up for votes.
Here are the five longest-serving current members of Congress, ranked by years in office:
Chuck Grassley, Senate, Iowa, Republican: 51 years served, in Congress since 1975, currently age 92.
Edward J. Markey, Senate, Massachusetts, Democrat: 51 years served, in Congress since 1975, currently age 80.
Harold Rogers, House, Kentucky, Republican: 45 years served, in Congress since 1981, currently age 88.
Steny H. Hoyer, House, Maryland, Democrat: 45 years served, in Congress since 1981, currently age 87.
Ron Wyden, Senate, Oregon, Democrat: 45 years served, in Congress since 1981, currently age 77.
Look at that list again. It's split evenly between parties, between chambers, between coasts. This isn't about one party clinging to power. It's about a system where staying is the default and leaving is the exception. Every person on this list has served at least 45 years. That means every single one of them was already in Congress before most Americans alive today were born. Three of them arrived in 1981, in the same freshman class, and forty-five years later they're all still there, still winning, still serving.
This is exactly why Too Damn Old exists. We're not here to tell you a 92-year-old senator or an 80-year-old senator is doing a bad job. Tenure and competence are different questions, and we don't pretend to answer the second one. What we track is the plain fact of time in office, because that number tells you something the news cycle usually doesn't: how deeply entrenched incumbency has become in a body that's supposed to turn over and reflect the country as it changes.
When you use this site, use the tenure numbers as a starting point, not a verdict. Ask yourself what 45 or 51 years in the same job means for accountability. Ask whether a Congress with this much institutional inertia can respond quickly to a country that looks nothing like it did in 1975 or 1981. Ask why the incentive structure in Washington rewards staying put for half a century instead of making room for someone new. These aren't partisan questions. They're structural ones, and the data is the same no matter who you vote for.
Think about what else has changed since these five started their careers. The internet didn't exist. Cell phones didn't exist. The Cold War was still on. And yet the seats themselves have barely moved. That's not a coincidence, it's a feature of how incumbency compounds: name recognition, fundraising networks, committee seniority, all of it stacks up year after year and makes the next challenger's job harder than the last one's.
The methodology here is simple and it's the same for every member in our database. We calculate years served using each member's official start date in Congress, whether that's the House or the Senate, drawn from public congressional records. Age is calculated from each member's publicly available birth date. We don't estimate, we don't round dramatically, and we don't editorialize about the raw numbers themselves. A member who has served since 1975 has served 51 years, full stop. That figure updates as time passes, and it applies uniformly across party lines and chambers, because the whole point of this project is a level, nonpartisan measuring stick that anyone can check for themselves.
This list of five is just the tip of it. If you want to see how every current member of Congress stacks up on tenure and age, and how the institution as a whole compares to the country it represents, the complete methodology and dataset live at toodamnold.com/data. Go look. The numbers speak for themselves, and once you've seen them, it's hard to look at Congress the same way again.
