The question: Election totals changed overnight. Does that prove cheating?
Changes in unofficial election totals do not, by themselves, prove fraud.
Election-night results are preliminary. Totals can change as eligible ballots are counted and results are checked.
Show me why
Counting, reporting and certification are different stages. Mail, provisional, military and overseas ballots may be processed on different schedules under state rules. A reporting update can therefore change the total or the apparent leader without changing any ballot. The time results appear online is not necessarily when voters cast those ballots.
A common misconception
A candidate leading in an incomplete count is not guaranteed to win the completed count.
Where the limits are
This does not establish that every election is error-free or rule out fraud in a particular case. Deadlines and procedures vary by jurisdiction; consult the relevant election authority for a specific contest.
How we know
The EAC describes canvassing as checking and resolving discrepancies before certification. Audits and recounts provide additional checks in applicable circumstances. To examine a specific allegation, use the jurisdiction’s rules, ballot reconciliation records, audit findings and documented discrepancies. A chart showing a sudden reporting jump is a question to investigate, not proof of an illicit cause.
What would change this conclusion?
Authenticated records of unlawful ballots, altered counts or other misconduct could establish a specific violation. They would add evidence beyond the mere fact that totals changed.
