1. They start counting the ballots on or before the Election Day
2. The state board of elections never provides a result on Election Day. They certify the count days or weeks later.
3. On Election Day, the state board provides to the public a partial, uncertified tabulation of votes as well as a tabulation of the remaining uncounted ballots that have been received.
3. If the partial, unofficial count on election night is definitive enough to make the winner at final tabulation and certification easy to predict, then and only then the news media (not the state board of election) reports this fact. Otherwise the news media will report that there has been no result. Typically the Associate Press takes the lead on interpreting the counts.
4. The new media will not claim a result if the number of uncounted ballots makes the result unclear.
Hence, there will be no flipping of any election night result. Or, at least, this is a very unlikely news media error and an error not made significantly more likely by the number of uncounted ballots.
I can’t believe that there is a Supreme Court justice who is so stupid that he does not already know this, Kavanaugh.
