Voter identification refers to the process of verifying a person's identity before they are allowed to vote in an election. Many states require voters to present specific forms of identification, such as a driver's license or a government-issued ID, to ensure that each person casting a ballot is eligible to do so. This practice aims to prevent voter fraud and maintain the integrity of the electoral process. The requirements for voter identification can vary significantly from one state to another. Some states have strict laws that mandate photo IDs, while others may accept non-photo identification or allow voters to sign an affidavit if they do not have ID. The debate surrounding voter identification often involves discussions about accessibility and the potential impact on voter turnout, particularly among marginalized groups.
