Early in-person voting changes when and sometimes where a ballot may be cast. Its effect depends on the number and location of sites, evening or weekend hours, transportation, and whether early options supplement or replace convenient Election Day access. Extra days may reduce congestion without adding many voters if people merely shift the day they participate.

The number of ballots requested cannot reveal how many were returned, questioned, cured, or counted. Classify the immediate stage first: identification concerns verification of the voter; early voting concerns the time and place of in-person access; mail rules govern casting, return, receipt, verification, cure, and counting.
