Absentee ballots are not counted until and unless the regular vote count is close enough to be changed by the absentee count.

For example, suppose the difference is 10,000 votes and the total number of absentee ballots is 12,000. In that case, the absentee ballots will be opened and counted.

On the other hand, if the difference is 20,000 votes, the absentee votes are left uncounted because they will not change the outcome even if all of them go to the candidate that is behind in the regular count.
