Lesson 1 covered the ways a member of Congress can leave. This one covers how the replacement arrives — and the two chambers do not follow the same rule. Pick a chamber and watch.
For the House, the rule is in the original 1787 document and it has never been amended. It gives the governor exactly one job: call an election.
That's the whole thing. No appointment. The Constitution Annotated says it plainly: the House Vacancy Clause does not contemplate a state executive filling a House seat temporarily. If your Representative dies, resigns, or is expelled, the seat sits empty until voters fill it. Sometimes for months.
The Senate rule looks almost identical — until the last twenty words.
That proviso is the entire difference. One sentence fragment, added in 1913, is why a governor can hand someone a Senate seat and cannot hand anyone a House seat.
Before 1913, ordinary citizens did not vote for senators at all — state legislatures chose them. The 17th Amendment moved the Senate to popular election, and while writing it, Congress carried forward a piece of the old system: the ability of a governor to fill a gap temporarily.
At the 1787 Convention there was no equivalent argument about the House. Delegates debated how Representatives would be elected, settled it, and never revisited how vacancies would be filled — because the answer was obvious to them. The people's chamber gets filled by the people. That clause has stood untouched for 239 years.
Everything. Vote on legislation, vote on nominations, sit on committees, filibuster. There is no asterisk on their vote and no reduced status of any kind. A seat filled by one governor's signature carries exactly the same power as one filled by three million ballots.
Nothing, in power. But an empty House seat means a district has no vote at all until an election is held — while a Senate appointment means a state keeps its vote, cast by someone no voter selected. Two different failures, and states choose which one they'd rather have.
Every date and figure below is from the public record. No grade is attached to any of it. This is what the sequence looks like when it happens to a real seat.
Two years into his second term, to become president of the University of Florida. The seat is vacant immediately.
Ricketts, who had finished his second term as governor days earlier, is selected after a formal application process — nine named applicants, each interviewed individually. No election is held. Four days from vacancy to appointment. Seat filled by appointment
Nebraska law requires the appointee to face voters at the next general election for the remainder of the term.
Defeats Democratic nominee Preston Love Jr. with 62.5% of the vote, for the remaining two years of the term. Seat filled by election
The first time this seat is contested for a complete term since 2020.
Between January 2023 and November 2024, Nebraska had two U.S. Senators. One had been elected by Nebraskans. One had been selected by one Nebraskan. Both cast identical votes on every bill in that period. That is not a loophole — it is the 17th Amendment working exactly as written, and it is the reason to know the rule exists.
One example can look like a quirk of one state. Here is the same clause, three years later, in a different state, triggered a different way — not a resignation this time, but a death in office. Watch how much of the sequence is identical.
At 71, after what his office described as a brief and sudden illness. He had been elected to office continually since 1992 and served in the Senate from 2003. Two days earlier he had been in Ukraine. The seat is vacant immediately — there is no waiting period and no acting officeholder.
Graham’s younger sister, and commissioner of the South Carolina Commission for the Blind since 2019. She had not previously held elected office. Two days from vacancy to appointment. No election, no confirmation, no hearing — the governor names a senator, and that is the whole procedure. Seat filled by appointment
Three days after the seat emptied, South Carolina has a sitting U.S. Senator again, with a full vote on everything the Senate does. She is the first woman to represent South Carolina in the Senate.
This is the part worth slowing down for. The appointment put her in the seat; the runoff is the first time any voter had a say in it. Six weeks separate the two. Voters weigh in
The appointment runs only to January 3, 2027. Everything past that date is decided by South Carolinians, not by the governor.
Nebraska’s vacancy came from a resignation and took four days to fill. South Carolina’s came from a death and took two. In both, one person’s signature seated a United States Senator, and in both, that senator later had to face voters to keep the seat. The mechanism did not care which state, which year, or what emptied the chair.
Go look at both seats yourself. The people in this lesson are on our map right now, with their real records and the phone numbers of their offices: South Carolina · Nebraska · California · Arizona. The Nebraska appointment has its own receipts trail in One Signature, One Senator, and you can sit in the governor’s chair yourself in the vacancy simulator.
It would be easy to read two Republican governors making two Republican appointments and conclude this is a one-party habit. It is not. Here is the same clause operating across both parties — including one case where the appointee chose not to run at all, and one where a single vacancy produced two unelected senators.
| Seat | Why it emptied | Who chose | What happened next |
|---|---|---|---|
| Arizona, 2018 | Sen. John McCain died in office, Aug 25 | Gov. Doug Ducey (R) named Jon Kyl, Sep 4 | Kyl resigned that December. The governor appointed again — two unelected senators out of one vacancy. |
| Nebraska, 2023 | Sen. Ben Sasse resigned, Jan 8 | Gov. Jim Pillen (R) named Pete Ricketts, Jan 12 | Won the 2024 special election with 62.5%. |
| California, 2023 | Sen. Dianne Feinstein died in office, Sep 29 | Gov. Gavin Newsom (D) named Laphonza Butler, Oct 1 | She announced 18 days later that she would not run for a full term. |
| South Carolina, 2026 | Sen. Lindsey Graham died in office, Jul 11 | Gov. Henry McMaster (R) named Darline Graham Nordone, Jul 13 | Won the Aug 26 special primary runoff; on the Nov 2026 ballot. |
Two Republican governors, one Democratic governor, and one governor who had to do it twice. Three deaths and one resignation. Every one of those senators was seated without a single vote being cast — and whether the voters got a say afterward, and how soon, came down to a state law most people have never read. That is the whole lesson. The rule is neutral. What it produces depends on who is holding the pen when a chair empties.
There is a detail here we did not go looking for, and it is worth a moment.
Eight years before his own seat emptied, Lindsey Graham stood on the Senate floor to eulogize John McCain — a senator who had died in office, and whose seat was filled ten days later by a governor’s appointment under this exact clause. Graham spoke on August 28, 2018. On September 4, Gov. Ducey named the replacement.
“I do not cry for a perfect man.” — Sen. Lindsey Graham, on the Senate floor, August 28, 2018, on the death of Sen. John McCain · reported by NPR, which is secondary — the floor speech itself is the record
On July 13, 2026, two days after Graham died, Sen. Chuck Grassley rose in the same chamber and did the same thing for him. That statement is published on Grassley’s own Senate website, which is why we can quote it rather than paraphrase it:
“His warm nature made everyone his friend, and I feel blessed to be one of them.” — Sen. Chuck Grassley, July 13, 2026 · grassley.senate.gov
Lindsey Graham said a great many quotable things across thirty-four years in Congress, and plenty of them were about the politics of the moment. Those do not belong in a lesson about how a chair gets refilled. Putting them here would be us picking a side while claiming to teach a rule. The two statements above are here for one reason: both are about this subject — a Senate seat emptying — and both are on the public record with a date and a place. That is the standard, and it does not bend for a good line.
