Staggered State Rules Leave Some U.S. Midterm Races Unresolved

Overview

• Most states released preliminary totals after Tuesday’s election, and partial returns show Democratic gains in aggregated counts, but several contests remain unsettled.
• The United States does not use a single national counting system so states set different rules for when mailed ballots arrive, how provisional votes are reviewed, and how counts are done.
• Alaska, Kansas, and Mississippi are expected to take the longest to finish because of separate processes and deadlines, including Alaska’s ranked‑choice redistribution scheduled for November 18 and its certification planned for late November.
• Kansas allows mail ballots postmarked by Election Day to arrive through November 6 and requires county reviews before a December 1 certification, while Mississippi accepts mail ballots through November 10 and plans a statewide declaration in early December.
• Because official certifications can lag, major media organizations are issuing winner projections based on partial counts and statistical models while voters, local officials, and candidates wait for final certified outcomes that will determine control of the House, roughly 35 Senate seats, and 36 governorships.
