NBC News Explains Expected Vote Estimate for 100% of Ballots in Races

2 articles · Updated · NBC News · Aug 19

NBC News said the “expected vote” is its estimate of the total ballots a race will have once counting is complete, not a fixed tally reported by election officials.
The estimate is built from several inputs, including early-vote totals and Election Day information gathered by NBC vote reporters from county election officials.
NBC said the figure can change as new information comes in, while vote data come via the Associated Press and projections are made by the NBC News Decision Desk.
