Mississippi Senate race hangs on thousands of uncounted ballots — with no recount law to fall back on

With roughly 1,800 votes separating them and thousands of ballots still uncounted, Mississippi's U.S. Senate race between Democrat Scott Colom and Republican incumbent Sen. Cindy Hyde-Smith is heading into a week of legal maneuvering — in a state that has no recount law and, according to election law experts, no formal procedure to contest a U.S. Senate general election at all.

As of late Thursday, Colom held 49.04 percent of the vote to Hyde-Smith's 48.85 percent, according to HuffPost. An earlier, more granular count by Transparency Cascade put the gap at just 65 votes — Colom 462,857, Hyde-Smith 462,792 — with independent Ty Pinkins at 19,938. The Secretary of State had not yet posted official 2026 general results on its results page, according to Transparency Cascade, and the count remains unofficial.

The outcome now depends on two categories of ballots still in motion. Mail ballots postmarked by Election Day, Nov. 3, can be counted if received by 5 p.m. on Nov. 10, under Mississippi law. Around 6,000 mail ballots appear to have been distributed but not yet returned before Election Day, according to data from the Mississippi secretary of state's office cited by NBC News. University of Florida Election Lab figures reported by Democracy Docket estimate roughly 6,500 additional ballots could arrive during the state's grace period, not counting military and overseas voters. For comparison, Mississippi counted 1,140 ballots that arrived after Election Day in 2024, according to Transparency Cascade.

An unknown number of affidavit ballots — Mississippi's version of provisional ballots — are also outstanding. Voters who lacked acceptable photo ID or were not found on the poll book cast these ballots on Election Day, and they have until Nov. 10 to present valid ID to their circuit or municipal clerk's office for their vote to count. The Mississippi Republican Party said roughly 17,000 provisional ballots could be outstanding, according to HuffPost. Mikell Bolden, the Mississippi Democratic Party's executive director, told NBC News the party's election hotline received around 2,000 calls on Election Day from voters who were told they had to cast affidavit ballots — many of them certain they were registered — after the secretary of state's website crashed, preventing voters from checking their own registration status.

The surge in affidavit ballots may be connected to a wave of voter registration deactivations before Election Day. Mississippi Today reported on Nov. 2 that over 230,000 Mississippi voters — about 1 in 9 — are now classified as 'inactive,' with county election commissioners doing the deactivating. Inactive voters can still vote but face additional hurdles, including filling out an affidavit ballot, the outlet reported. The Secretary of State's office had not answered questions about the spike, according to Transparency Cascade.

Both campaigns are preparing for a legal fight. Colom said at a Wednesday news conference that his team has been preparing for months. Staff from the Democratic Senatorial Campaign Committee and the Elias Law Group — which serves as the Colom campaign's lawyers — are on the ground in Mississippi, according to NBC News. Hyde-Smith's campaign manager, Jake Monssen, said the campaign is 'closely monitoring the remaining count' and is confident she will prevail. The National Republican Senatorial Committee said it is 'committed to ensuring that every single lawful ballot is accurately counted.'

We're prepared to litigate, though we were prepared for this for months. We have an army of lawyers. We have local lawyers. We have everybody involved to make sure the process is followed according to the law.— Scott Colom, Democratic Senate candidate

What makes this race particularly complicated is what Mississippi law does not provide. There is no automatic recount mechanism, and recounts happen only by court order, according to the AP. Nor is there a formal contest procedure for a U.S. Senate general election under state law or the Mississippi election handbook, according to NBC News and Transparency Cascade. Ben Griffith, a voting rights and election law attorney who teaches at the University of Mississippi, told NBC News that candidates can technically challenge results county by county by filing with individual county clerks to examine ballot boxes — but with 82 counties and nine days until canvassing must be complete, he called that 'beyond the scope of feasibility.' Any meaningful challenge would go to a court, and above the state courts sits the U.S. Senate itself, which has the authority to judge the elections of its own members.

The legal landscape around Mississippi's mail ballot grace period was itself recently settled by the Supreme Court. In June 2026, the Court ruled 5-4 in Watson v. Republican National Committee that federal election-day statutes do not set a deadline for ballots to arrive — reversing a 5th Circuit decision that had sided with the Republican National Committee and the Mississippi Republican Party. Justice Amy Coney Barrett wrote for the majority: 'The election-day statutes say nothing about ballot receipt, and we cannot add to the words Congress chose.' Justice Samuel Alito dissented.

The scale of the Democratic shift in Mississippi adds context to the razor-thin margin. Transparency Cascade's county-level analysis found that all 82 Mississippi counties moved toward Colom compared to the 2024 presidential race, with a median shift of 18.9 points — in a state Donald Trump carried by about 23 points in 2024. Nationally, the Senate vote moved toward Democrats in 2,156 of 2,177 counties across 30 states. When a wave that large produces a near-tie, Transparency Cascade noted, 'the margin no longer settles the race. The rules do.'

Counties must transmit results to the secretary of state by Nov. 13. Mississippi's Senate race is one of two Senate contests still unresolved nationally — Alaska's race between Republican incumbent Sen. Dan Sullivan and Democrat Mary Peltola is also uncalled, with Peltola leading by roughly 640 votes as of Thursday evening, according to HuffPost. Alaska uses ranked-choice voting and counts mail ballots received up to 15 days after Election Day, with election officials targeting Nov. 25 to certify results.

Why it matters — A Democratic win in Mississippi would be one of the deepest red-state Senate flips in recent memory, but the outcome hinges on arcane ballot-counting rules and a legal landscape with no clear recount path — setting up a potential court battle over which votes count.
