A provisional ballot is a special type of voting method used when there are questions about a voter's eligibility. This can happen if a voter’s name is not on the registration list or if they do not have the required identification. The provisional ballot allows the voter to cast their vote, which will be counted once their eligibility is confirmed. After the election, election officials review the provisional ballots to determine if they are valid. If the voter is found to be eligible, their vote is included in the final tally. This process helps ensure that every eligible voter, including those facing issues, can participate in the electoral process.
