No. There will be no runoff in Mississippi's U.S. Senate race, however close it finishes. This is a regular federal general election, and under Mississippi law a candidate for federal office needs only a plurality — more votes than anyone else — not a majority of 50 percent plus one. Secretary of State Michael Watson's office has confirmed exactly that, so when the count between Democrat Scott Colom and Republican Senator Cindy Hyde-Smith finally ends, the candidate in front takes the seat, even if neither reaches 50 percent.
The numbers explain why so many people are asking. On Friday the Associated Press put Colom ahead by nearly 2,500 votes, at about 49.1 percent to Hyde-Smith's 48.8 percent, with roughly 30,000 ballots still estimated to be out. Independent Ty Pinkins holds about 2.1 percent — some 19,900 votes, roughly eight times the gap between the leaders. With Pinkins in the race, neither leader is going to reach 50 percent, and voters who know Mississippi for its runoffs have naturally assumed a second election must follow. It will not.
The plain reality is that Mississippi runs different kinds of elections under different rules, and the runoff rule people remember does not belong to this one. Party primaries in Mississippi go to a runoff when nobody wins a majority. So do the state's own statewide offices — governor, attorney general and the rest — ever since voters approved a constitutional amendment in 2020 that replaced the old 1890 system with majority voting and runoffs. And this very Senate seat went to a runoff the last time it was open under special rules, in 2018. But the Secretary of State's clarification draws the line where the law draws it: the eight statewide state offices require a majority, while federal offices — President, U.S. Senate and U.S. House — require only a plurality.
"Despite a widespread belief to the contrary, Mississippi will not host a runoff in its race for the U.S. Senate this fall." — The Downballot, reporting the clarification election officials issued after the confusion spread
The 2018 race is the source of the confusion, and its details prove the point. That was a special election, and Mississippi special elections are nonpartisan: every candidate runs on one ballot, and a majority is required. Hyde-Smith finished first with just 41.2 percent, ahead of Democrat Mike Espy at 40.9 percent, with Republican Chris McDaniel taking 16 percent — so a runoff was held later that month, and Hyde-Smith won it 54 to 46. None of that machinery applies this year, because this is a regularly scheduled general election. Mississippi has in fact sent a senator to Washington on far less than half the vote before: in 1978, Republican Thad Cochran won this same seat with 45.3 percent, in a three-way race, and served for four decades.
The common-sense principle is simple: the rule that decides a winner is the rule written for that kind of election, not the rule voters remember from a different one. A runoff is not a fairness device that appears whenever a race is close; in Mississippi it exists only where the law puts it — in primaries, in special elections and in races for state office — and the law does not put it in a federal general election.
So the consequence is that there is no second campaign and no December election day waiting behind this count. Everything rides on the ballots still being processed: mail ballots postmarked by Election Day can arrive through Tuesday, November 10, voters who cast affidavit ballots for lack of photo ID have until the same day to show ID, counties must certify by November 13, and the Secretary of State declares the final result on December 3 — the timetable laid out in our report on when the Mississippi race will be called. Because there is no runoff, and because Mississippi has no recount law either, the leader on the final certified count wins a six-year term outright — likely with about 49 percent of the vote. Which raises the question that follows from it: if a seat this important can be won without a majority, is the real contest now the fight over which of the remaining affidavit ballots get counted at all?
Hyde-Smith, trailing as the last ballots are checked, is not speaking like a candidate preparing for any second round. She posted her position on X for everyone to see: "Cindy Hyde-Smith is going to represent Mississippi in the United States Senate for the next six years."
