Thousands of Mississippi voters may have their ballots thrown out this week after a Republican-led voter roll purge booted them from precinct poll books — and the outcome could decide a U.S. Senate seat that remains too close to call.
Democrat Scott Colom holds a narrow lead over Republican Sen. Cindy Hyde-Smith, but the final count hinges on whether provisional ballots, called affidavit ballots in Mississippi, survive the certification process. Both campaigns say thousands of voters were affected. Counties have until Friday to vet those ballots and certify results. The state deadline is December 3.
The machinery behind the mess: Secretary of State Michael Watson oversaw a list-maintenance effort that used commercially available credit data from Experian to flag voters who may have moved. Before Election Day, more than 230,000 voters — roughly 1 in 9 statewide — were placed in inactive status and excluded from local poll books, according to Mississippi Today.
Experian itself wants nothing to do with it. The company told CNN its product "was not designed or intended to validate voter records" and said it hasn't worked with the state since early 2025. Critics point out that in a state where more than 9 percent of residents don't use a bank, credit data is a shaky foundation for determining who gets to vote and who doesn't.
Watson defended the purge as a way to block "dead people, illegal aliens with fake addresses, or nonresidents" from voting. He called the affidavit ballot process "a safety net for errors election commissioners make during voter roll maintenance."
For voters like Andrew Couch, that safety net failed. Couch had voted at the same polling location in the last two elections, but on Election Day he was told he was registered in a county he hadn't lived in for six years. He cast an affidavit ballot. On Monday, he learned it would not count. "I'm very upset," Couch told CNN. "If people lose faith in the process that we're going through, I think it's going to hurt voter turnout in general in the future."
As of Monday evening, Watson said 15,547 affidavit ballots had been processed and roughly 76 percent were accepted. Another 2,578 absentee ballots remained outstanding. County election officials told CNN that voter ID issues accounted for a relatively small share of provisional ballots — meaning the roll purge, not ID requirements, is the main driver.
Election law experts say Mississippi stands apart from most states. Many states allow inactive voters to cast regular ballots at their correct precinct, and federal law keeps them eligible for two federal general elections. "Mississippi short-circuits the process by hastily excluding you from the poll book," said Michael Morse of the University of Pennsylvania's law school.
CNN framed the dispute as part of a broader Republican push on voter rolls, noting the party has "zeroed in" on list maintenance at federal and state levels. Raw Story led with the political stakes and the purge's mechanics. Neither outlet spent much time on the basic question: why is a state using credit-reporting data — that the credit reporter itself disavows — to decide who appears in a poll book on Election Day?
Friday's county certifications will show how many of these ballots survive. Until then, one Senate race and tens of thousands of voters wait on a process that Experian already walked away from.
